Arsenal and Atletico Madrid scored a penalty each in an incident-packed first-leg draw that leaves their Champions League semi-final in the balance.
Viktor Gyokeres won and scored a spot-kick for the visitors just one minute before the break after he went down under a challenge from David Hancko.
But Julian Alvarez levelled the score 11 minutes into the second half with a penalty awarded following a video assistant referee review.
The game started as a cagey affair with neither side looking to give away an advantage.
But after Gyokeres put the Gunners in front, Atletico Madrid started the second half by piling on the pressure.
Ademola Lookman forced David Raya into a save before Gabriel Magalhaes produced an excellent block to deny Antoine Griezmann from the rebound as the hosts looked for an equaliser.
Atletico got a penalty when Marcos Llorente’s shot from the edge of the box hit Ben White’s leg and then touched his hand.
The referee pointed to the spot after a VAR check, with Alvarez slamming the ball into the top corner.
Griezmann hit the crossbar before Lookman had a golden chance to score a second for Atletico but the winger could only shoot straight at Raya from close range.
Substitute Eberechi Eze thought he had won Arsenal’s second penalty late on when he appeared to beat Hancko to the ball inside the area but the decision was overturned after a VAR check.
The tie is now finely balanced before the two sides meet in the second leg in London next Tuesday.
