After his great overhead kick found the net to break the deadlock in a difficult match, all Olivier Giroud could do was wait. And wait and wait. Giroud's 68th-minute bicycle-kick goal against Atlético Madrid was initially disallowed for offside and it took nearly three minutes for video review to reverse the call and secure Chelsea the 1-0 away win in the first leg of the round of 16 of the Champions League on Tuesday. Giroud was clearly in front of the defenders when he pulled off his acrobatic shot and few Chelsea players complained when the linesman raised his flag, but VAR determined that the ball came from Atlético defender Mario Hermoso instead of Chelsea midfielder Mason Mount, thus annulling the offside.

"I did not know what to think about the goal, I just focused on hitting the overhead kick and was pleased to see it go in the back of the net, I had no clue about being offside," Giroud said. "Mason Mount said he did not touch the ball. Good for the team, good for me." The result kept Chelsea coach Thomas Tuchel unbeaten in eight matches since he took over the squad to replace Frank Lampard. "Fantastic result, fantastic goal. Well deserved," Tuchel said. "It was a very disciplined performance  a deserved shutout." Atlético was the home team but the match was played in Bucharest, Romania, because of travel restrictions preventing visitors from Britain entering Spain.
