Stuttgart's first pass through Stiller can bring Undav into the spaces behind Atlético's midfield. Atlético have also shown they can sustain possession away from home, then reach Baena and Alvarez around the box. The contest turns on who collects the next ball after Stuttgart's wide delivery and how quickly the back line resets.
Stuttgart created plenty against Hamburg despite failing to score, and their wide service can feed Demirović after Undav draws a defender. Atlético's Barrios and Hjulmand have already worked together without Koke, screening central passes and recovering the next ball. Koke also missed recent matches; Romero played against Espanyol before becoming unavailable, leaving a new central defensive assignment alongside Hancko. Stuttgart's Jeltsch and Chabot both played Hamburg, where the home side still allowed substantial chances, while Atlético built long attacking spells at Espanyol and Alavés. That blend of midfield recoveries and settled possession gives Baena and Alvarez more than one route to a clean finish, so I'm siding with Atlético Madrid to win this match.
