He has never had the pace to be a competitive RB in the world. He is a danger at set pieces, yes. Can be good going forward, by sheer physicality and one on one takeonsm still he isn't a RB. Or atleast he needs some rest. And IMO if Azpi is going to go left back and stay there, than atleast Clyne can fit right in. Being a RB or a LB is one of the biggest roles in football. I know, cuz I have played, and it was tiresome at that level, let alone Bpl. Let's be honest, being able to constantly be forward and back isn't something a brute like Ivanovic can do regularly nowadays. And I said it after the game at Old Trafford. If we are to play attacking football, then playing with a Stamina and pace Stacked(let's say that) RB/LB is something WE NEED. AND if Filipe isn't going to be a starter any time soon, we will have problems in the right hand zone, no matter Willian's help there.
