Marcus Thuram scored an injury-time winner to hand Inter Milan a narrow 1-0 win over Young Boys in the Champions League.
The substitute got in front of his marker to turn in Marko Arnoutovic's cross in the third minute of injury time.
It marked a moment of redemption for Arnautovic, who missed a penalty earlier in the second half after Jaouen Hadjam was penalised in the box for dragging down Denzel Dumfries by the neck.
Arnautovic's strike lacked power and Young Boys keeper David von Ballmoos guessed the right way, parrying the ball away before reacting quickly to stop Dumfries from burying the follow-up.
The result leaves Inter Milan with seven points in the league phase of the Champions League, while Young Boys remain without a point after three games.
In an entertaining encounter, the Swiss dominated and were unlucky not to score in the first half, with efforts from Jaouen Hadjam and Lukasz Lakomy forcing Yann Sommer into two fine saves.
Benjamin Pavard was needed to block a bullet header from Alan Virginius, while Joel Monteiro should have done better when he slammed his strike over the bar after finding himself through on goal.
Monteiro continued to threaten after the break as he danced past defenders before being denied by the woodwork, while he drilled another effort just wide.
