Actually there is need of another midfielder.Fabregas isnt really a CM and comparing anyone with Xavi is irrelevant.Fabregas is a clear attacking midfielder and performs better in that role.The problem with our midfield is that we dont have too much defensive power in it,Xavi and Iniesta cant provide cover.The best thing for us would be a player like Gundogan who works as box to box and has defensive and attacking abilities..Cesc or Sergi Roberto can rotate with Xavi. People need to let go of the "Xavi role", the team will have to find a slightly different way of playing without him. There's no need for another midfielder, unless it is to warm the bench.
