On frustrated supporters potentially returning to the Emirates on Thursday, Aubameyang told BBC Sport: "What can I say?" "Because I want our fans to behind the team and be happy. I think the penalty is a key point in the game because if Troy scores we come back to 2-1 and the game changes completely but he missed it and we are very disappointed".
Watford manager Javi Gracia lamented his team's profligacy in front of goal, and said that the game had been too open for his liking.

And they're [rules] a bit ....not maybe stupid but something like that.
He has therefore been forced to sit out of both legs against Swedish side Ostersund as well as the trip to face boyhood club AC Milan last week, a game the Gunners won 2-0. It is even more annoying for Aubameyang because the Europa League has come to represent Arsenal's only hope of salvaging what has been a dismal season.
