I'd actually say we need to replace our 'spine'. and I mean Aguero, Yaya and Kompany.
Yaya is past it and can't play every week, nor can he play a 2 man midfield against high energy teams. He still can be incredible for us, but not over the amount of games we need.
And, before you kick the shit out of me for saying Aguero and Kompany. Look at who you would consider the aguero and kompany of Real, Barca or Bayern. Then, compare how often they are out injured. They are the best Striker and CB in the premier league, however, they seem forever in a loop of 'injured-coming back-niggle-injured'. We can't keep pinning all our hopes on Aguero and Kompany to not be injured, all it takes is a look through our pre game threads to see we regularly do this. It's fucking shit, but it's true.
