#2 Koke vs Bouna Sarr
Bouna Sarr has been one of Marseille's best defenders this season, and any hopes of them stopping Atletico rested on the pairing of him and Gustavo. While Gustavo failed to live up to that expectation, Sarr was easily their best player on the pitch.
For the most part, he dealt with Koke's marauding runs down the left flank but found himself overwhelmed by Atletico's crowding of the ball. With centre-back Rami fully occupied with trying to keep Diego Costa silent, Sarr was overworked in his attempts to keep up with his opponents on the evening.
Koke, yet another staple of Simeone's Atletico, had his skills on full display. Acting as the bridge between attack and defence with his distribution, he was pivotal in creating two of Atletico's three goals on the evening.
First, he found Griezmann with the perfect ball during a counter to bag Atletico's second goal of the night. Then, he waltzed into the Marseille box and squared a pass to captain Gabi, who put the game well and truly beyond their reach.
