I agree, he won't be a bench warmer and he'd play a lot more games thank some may think.
I said it earlier in this thread. Pick 3 starters from of Ruben, Johnny, Ake, Akanji, Kyle and maybe Eric or his replacement if he leaves. We can then have Rodders and Rice in front with Rice doing the Johnny role and slotting into the backline when defending. No loss of quality and more options to rotate in a 60+ game season.
The bonus is that we can then pick 5 attack minded players rather than the 4 we deploy now (3 across the pitch with Erl up top). Imagine that for a minute.
