Arsenal drew 2-2 with Bayern Munich in the first leg of their Champions League quarter-final on Tuesday night.
Bukayo Saka gave the Gunners an early lead with a curling finish.
However, the Bundesliga champions capitalised on poor defending to equalise against the run of play through former Gunner Serge Gnabry soon afterwards.
Former Tottenham striker Harry Kane then coolly dispatched a penalty for his 15th goal in 20 games against Arsenal after Leroy Sane was felled by William Saliba.
Arsenal found a leveller through Leandro Trossard when he swept home a pass from fellow substitute Gabriel Jesus in the second half.
