Ah I see, I think we'll accomodate the two by playing the diamond formation (where we've generally looked our best) with Balotelli and Sturridge up as a front two, both can drop back to pick up the ball, play on the last man and pop up in wide positions fairly well so I can see them alternating between those roles. As for Sturridge's selfish side, I think he showed when partnering with Suarez he can work well with a strike partner (Suarez showed he too can curb his selfish side with a partner), the selfish side comes out more when he's up on his own and maybe he feels the onus is on him to score the goals for the team. But im not really anticipating any sort of personality clash with him and Balotelli.
But I can also see us reverting to just one up front in games where we absolutley need more men in midfield with Sturridge being the preferred striker as his workrate (also something he was critiscised for before he joined us) is better tha Balotelli's
