Arsenal midfielder Granit Xhaka insists they should stick with their back three system.

Arsenal have won four of their last five games since switching formation to a back three last month.

Xhaka feels they should keep the system for the rest of the season. He explained: "It doesn't make a difference for me if you play with three at the back or four.

"I played for a year at Monchengladbach with three at the back. Of course it's a different role but so long as things are going well, why change?"
