Wenger has totally lost it. He played 3 at the back against the quickest wide forwards in the Premier League and dropped Lacazette and Giroud against a defence that struggles with crosses. And also played other players out of position. First game for Sanchez but he looked well off the pace. I feel we are in for yesterday's man and it would be a really bad decision to buy him when Aguero is also struggling with the same issues. The other aspect of Sanchez's game at Arsenal was that he was played as a deep forward in the Silva, De Bruyne position. We do not need another player in that position. We could do with an out and out forward but Sanchez has reached the age where he is dropping deeper to find space. Of the forwards we are linked with, Aubameyang suits us better, but I'd be very surprised if Dortmund sold him having sold Dembele.
