Arsenal midfielder Granit Xhaka: No reason to change back three

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?"
