Rennes can keep pushing the ball wide, while Olympiacos are built to make the final shot difficult. The French side's pressing creates useful early service into the box. Olympiacos have shown they can absorb that pressure and still threaten from a restart or a second ball. In the other match, Nasaf's territorial control meets Al Kuwait's sharper box finishing from their recent meeting.
Haise's Rennes found Dia and Szymański through Nagida and Frankowski against Strasbourg. Olympiacos restricted Marseille and Sparta, with Retsos, Hezze and Ortega protecting the final contact; Chiquinho's delivery also gave them a scoring route. Rennes have already played without Lepaul, and Olympiacos have used Yaremchuk and González without El Kaabi. As Rennes press and work the wings, I expect Olympiacos to contest the next ball and preserve enough control. That's why I'm siding with Olympiacos.
Nasaf took more shots in the previous meeting, but many ended outside the box or were blocked. Al Kuwait reached the box more cleanly, with Ali Hussain supplying Daham and Daham taking all three of their shots on target. Gonzalez and Barrahma played that meeting and are now unavailable, while Nasser returns as another finishing option. Nasaf should push for the second ball, leaving Kuwait chances to release Daham again. That's why I'm siding with Al Kuwait.
