Xhaka possesses none of the credential Arsenal need his lack of stamina effects his ability to move up the pitch and distribute the ball and hence close the opposition down, his poor
acceleration put him in at a massive disadvantage in taking on the one on one chase back toward his goal, his
sluggish tackling causes him to get sent off and his poor positioning allow the opposition plenty of space to exploit,
Xhaka overall style of play is going to cause Arsenal huge problems for the foreseeable future.
The problem with
Xhaka is this, he tend to sit deep in his own half allowing the opposition players time and space to get a good run on him and hence test his
sluggish acceleration and pace, his also not prepared to get engage with one on one chase with attacking players who runs at him with the ball, he tend to foul the opposition player and get yellow or even worst red card on a consistent bases.
