Arsenal manager Arsene Wenger insists Granit Xhaka is not a dirty player despite the midfielder's indifferent start to life in England.
The 24-year-old arrived at Arsenal from Borussia Monchengladbach in the off-season with a reputation as a rough player.
Xhaka has been sent off in the Premier League and he gave away his latest penalty in a 3-3 draw against Bournemouth last time out.
But Wenger believes the Switzerland international is showing improvement defensively, denying claims he is dirty.
"You can see in his game he is not a dirty player. Overall I am quite happy with his defensive evolution," the Frenchman said.
