Despite some improved performances from the midfielder, his costly lapse in concentration against Wolves was a reminder of his main deficiency
Granit Xhaka is an Arsenal enigma. Bought for £30 million ($38.6m) from Borussia Monchengladbach with the billing as the youngest captain in Bundesliga history, Xhaka has managed to turn in as many show-stopping performances as he has deeply frustrating ones.
No better was that illustrated than against Wolves on Sunday. The 26-year-old came into the match on a high having put in arguably his best performance in a Gunners shirt against Liverpool last time out in the Premier League.
