With a goal from Marko Arnautović, Inter Milan managed to take the lead (1-0) as the home team in the first leg of the UEFA Champions League round of 16 against an Atlético Madrid side that resisted but did not pose a threat in attack.

In the 79th minute, the forward, who replaced Markus Thuram after the break due to injury, took advantage of an error by Reinildo, who failed to connect with Rodrigo de Paul in the center of the field. They both lost possession of the ball, which reached Lautaro. The Argentine shot, Oblak deflected, and Arnautovic picked up the rebound to score.
