Arsenal manager Arsene Wenger believes that the arrival of Borussia Dortmund striker Pierre Emerick Aubameyang might have something to do with Alexander Lacazette's dip in confidence.
This is what the Wenger had to say on Lacazette ---
_"For him, one against one with the goalkeeper, he is a good goalscorer. He has gone through difficult periods before. He works hard in training, works on his finishing. I don't know what happened, did he not touch the ball well? It can happen, it is a fraction of a second.
Maybe the confidence is not at its highest because he has seen a competitor coming in for him."_
Arsenal will play Ostersunds in the last 32 of the Europa League on Thursday
