[2026-27 UEFA Europa League] Olympiacos vs Sparta Prague preview and analysis Kick-off: October 22, 19:00 UTC
Olympiacos host Sparta Prague at the Karaiskakis Stadium in Piraeus for Matchday 3 of the UEFA Europa League league phase on October 23 at 04:00 Korea time. It is the clubs’ first competitive meeting. Olympiacos will look to extend their perfect start, while Sparta Prague seek a response away from home after two straight draws.
1. Match overview and team form
Olympiacos have six points from two Europa League matches, with three goals scored and one conceded, placing them 10th. Sparta Prague are 11th with four points, five goals scored and two conceded. The gap is small, but neither side has faced a team currently near the top of the league phase. Jagiellonia Białystok and Marseille, whom Olympiacos beat, are both in the lower half, as are Ararat-Armenia and Lillestrøm, Sparta Prague’s opponents. Their European results alone do not tell us which side is stronger today.
Europa League: Olympiacos 2 wins, 3 goals scored, 1 conceded / Sparta Prague 1 win, 1 draw, 5 goals scored, 2 conceded Domestic league: Olympiacos 2nd, 16 points / Sparta Prague 5th, 8 points behind the leaders Recent competitive form: Olympiacos have won 5 in a row / Sparta Prague have drawn their last 2 Recent home and away form: Olympiacos have scored 7 and conceded 5 in their last 10 home matches / Sparta Prague have scored 12 and conceded 11 in their last 9 away matches
Olympiacos’ five-match winning streak has not been built on a glut of goals. They had 23 shots and scored twice against Jagiellonia Białystok, then beat Marseille away 1-0 through Santiago Hezze’s header from a short corner. Stefan Ortega’s saves and Panagiotis Retsos’ defending helped them protect the lead in the second half. Since Imanol Alguacil took charge, their five wins have come by scores of 1-0 three times, 2-1 once and 2-0 once. Olympiacos failed to score in five of their last 10 competitive home games, but conceded only five across those matches. Alguacil has only overseen two of those 10 home games, so that longer record does not all belong to his tenure.
Sparta Prague’s five-match winning run was followed by draws against Lillestrøm and Baník Ostrava. They had 15 shots against Lillestrøm, put eight on target and scored only once, then conceded an equaliser in stoppage time after a mistake by Tobias Guddal. Their 4-1 away win over Ararat-Armenia showed their attacking threat, but they also had an expected goals against figure of 1.93. Their recent scoring struggles and the fact that they have conceded after taking the lead in both Europa League matches need to be considered together. They have also conceded at least twice in each of their last three away games against strong opposition.
The differences in availability are more direct. Leon Bailey and Kostas Fortounis are out for Olympiacos, though neither was expected to start in the Europa League. Their absence leaves fewer options for dribbling down the flanks and for set pieces during the match. With Ayoub El Kaabi and others not registered for the competition, Roman Yaremchuk and Armando González are the options up front. Alguacil has kept 9 of the same 11 starters across Olympiacos’ first two Europa League matches, and is expected to use a similar 4-2-3-1 to the one against Marseille.
Adam Karabec, Matěj Ryneš, John Mercado and Adam Ševinský are unavailable for Sparta Prague. Karabec and Ryneš had already missed the last three matches. The latest loss is Mercado, who has scored four goals in seven appearances this season. Mercado finished a cross from Ryneš against Lyon, while Karabec’s corner led to Guddal’s goal against Ararat-Armenia. The wide supply and finishing combination will have to change. Matěj Jurásek, expected to replace Mercado, has set up a goal with a cross before, but his role is different from Mercado’s, who would be on the end of those deliveries.
In defence, Martin Suchomel is expected to move from the right to the left to cover for Ryneš. Guddal and Jaroslav Zelený are tipped to partner in the middle. They have played together in the last two matches, so the pairing is not new. Loïc Mbe Soh is back, though it is unclear whether he will start. Both teams are playing their fourth competitive match in 12 days. Based on the predicted line-ups, though, seven Olympiacos players did not start their league match on October 18, while 10 Sparta Prague players did.
The teams have no head-to-head history. Nor does the record of Czech clubs going winless in 19 UEFA away matches in Greece explain the tactics or personnel in this game. Sparta Prague did not train at the stadium, holding their final tactical session in Prague instead. Most of the squad will first step onto the pitch during the pre-match warm-up. We cannot know how much that choice will affect the result, but it is worth watching how they handle passes in their own half early on. The forecast at kick-off suggests rain and wind will not be strong enough to change the way the game is played.
2. Match-up analysis
The key contest is Olympiacos’ press against Sparta Prague’s build-up from the back. Brian Priske wants his side to play out with passes, while Alguacil described Sparta Prague as a team that builds from the back. Priske, in turn, called Olympiacos’ press strong and aggressive. If Sparta Prague can work the ball through Guddal and Zelený, Hoshimar Alcácer could receive it behind Olympiacos’ press. But losing the ball in their own half would give the hosts chances close to goal.
Sparta Prague could also use long balls to bypass the press. That would reduce the risk of losing possession near their own goal, but could give Olympiacos more chances to win the ball back and attack down the flanks or from set pieces. Sparta Prague’s concern is not only the central defensive pairing, but also Suchomel’s switch to the left and the short rest for the defenders in the starting line-up. If Suchomel is often left to deal with the opposition’s wide attacks alone, Saliakas and Jota Silva could find chances to cross from that side. It will also matter how the changes Priske has previewed ease the burden on his defence and midfield.
More crosses from Olympiacos do not automatically mean more goals. All three of their Europa League goals have come from set pieces or crosses, but Sparta Prague have players such as Guddal who can compete for the first ball in the air. Olympiacos will need another route beyond the initial header. González scored from the loose ball after a corner against Jagiellonia Białystok, while Hezze turned a short corner into a header from a cross at a different angle against Marseille. Sparta Prague’s response after clearing the first ball will matter: can they hold their shape and deal with the next pass and shot?
At the other end, Guddal’s aerial threat is Sparta Prague’s clearest route to goal. He headed in Karabec’s corner against Ararat-Armenia, then scored again from the loose ball after the next corner. Karabec, who delivered that first ball, is unavailable, as is Ševinský, another aerial target. Guddal remains a threat if Roman Macek delivers an accurate set piece, but whether someone else can create chances when Olympiacos focus on marking Guddal is another question. In open play, Alcácer’s dribbling matters. He beat a defender and set up Mercado against Ararat-Armenia, then came off the bench to score against Lillestrøm. This time, Mercado will not be there to finish a pass after his run.
How the teams manage the game after the first goal could also separate them. Olympiacos gave Marseille more of the ball after going ahead and strengthened the midfield. They also held on to a 1-0 lead against Panathinaikos while a man down. Sparta Prague, meanwhile, have conceded after taking the lead in both of their Europa League matches. If Olympiacos score first, Sparta Prague’s push forward could leave room for counterattacks down the flanks. Alguacil has so far preferred to protect a lead rather than keep adding attackers, though. If Sparta Prague get through the early stages without conceding and deal reliably with aerial balls, Olympiacos may have to wait for a goal even if they dominate possession.
3. Verdict and conclusion
We see Olympiacos taking control and winning 1-0 as the likeliest outcome. If Sparta Prague stick to building from the back, they will face pressure from a more rested Olympiacos side. If they go long, Olympiacos may get more chances to attack again. The hosts will look for an opener by winning the ball in the opposition half or from a second phase after a set piece.
After that, we expect Alguacil to reinforce the midfield and protect the lead. Without Mercado and Karabec, Sparta Prague will need to redistribute their usual roles in wide attacks and from corners. Olympiacos also rely on crosses, which will meet Sparta Prague’s aerial defence, so even if the hosts control the game, a second goal may not come quickly. If Sparta Prague push forward in the second half in search of an equaliser and leave space behind Suchomel on the flank, Gelson Martins and Jota Silva could help make it 2-0.
The market has leaned towards a home win, reflecting Olympiacos’ winning streak and home advantage as well as Sparta Prague’s absences, and prices moved towards a wider margin during the observation period. We agree on the likely winner, but expect a narrower scoreline. Sparta Prague’s absences reduce their scoring routes as well as their chances of winning, while Olympiacos have tended to protect a lead rather than push for more goals. That outlook changes if Sparta Prague withstand the early pressure and turn one of Macek’s set pieces into a goal for Guddal.
