Arsenal manager, Mikel Arteta, has said his side was affected by Bayer Leverkusen’s goal, as they drew 1-1 in the Champions League last-16 first leg on Wednesday night.
Robert Andrich opened the scoring for the hosts from a corner-kick, before a late Kai Havertz penalty ensured the game ended in a draw.
The result brought Arsenal’s perfect run in the competition to an end ahead of the second leg. 
Arteta said: “The game had very different periods… we started the game quite well, then they scored and the game changed completely.
“In the 2nd half we had to stay emotionally under control and very composed.
“In the end we found our way to draw the match.
“Football gives us very nice and funny stories… I was impressed by how composed Havertz was when he took the penalty.”
