The Gunners battled from behind to beat Everton, Norwich and Swansea in the space of six days, something that Xhaka believes puts to bed any question marks over Arsenal's attitude.
"It's the third time in a week that the team have come from behind to win, that says a lot about this team," Xhaka told 'arsenal.com' after the 2-1 victory over Swansea.
"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."
