The Gunners have found themselves a goal down to Everton, Norwich City and Swansea City in league and cup over the past seven days, bouncing back to make it 10 victories in their last 12 outings.
Xhaka believes that Arsenal's character has been made clear for all to see of late, having been criticised by Watford skipper Troy Deeney earlier this month for 'lacking cojones' in their 2-1 loss at Vicarage Road - their only setback since August.
Speaking after the most recent of the victories, a 2-1 win over Swansea City on Saturday afternoon, the Swiss midfielder told reporters: "It's the third time in a week that the team have come from behind to win, that says a lot about this team. Lots of people talk about the character of our team, that it's not right and that we need to do more. But we always show that we can come back.
"Today we were 1-0 down, last week we were 1-0 down, but we turned the games around and that shows the character of this team. The manager told us at half-time that we had to give more, that we had to be more aggressive and play quicker.
"You have to pay compliments to Swansea - they stood deep in the first half and were good defensively. In the second half, we played as we know we can and it was very important for us to win."
Arsenal are back in action next Thursday with a home match against Red Star Belgrade in the group stage of the Europa League.
