I think Rafa if you look through his career prefers a different kind of striker for the starting position - Torres, Kuyt, Mista, Eto, Higuain etc etc. He quite likes a tall or robust striker for the bench. Crouch, Milito and so on. He plays pretty much the same way wherever he goes so I think Mitro will have to settle for short bursts of 3 games on the bounce here and there to allow Gayle to rest.
