Looking at the current situation at United with V persie arriving and pushing their star striker Rooney to a midfield role, it does worry me a bit because it might just kill Suarez' momentum and he will start having a goal drought. I think Sturridge should earn the right to play upfront instead of just walking into the team like that. Suarez would remain my CF if I had my way.
Sturridge doesn't need to earn the right - BR paying £12m for him has 'given' him the right to play upfront. What Sturridge needs to do is earn the right to 'stay' there.
Although Suarez appears to play centrally up front according to the TV team sheet graphics, he actually plays in a free role. Whether he starts out wide or behind Sturridge he'll do exactly what he always does. With Sturridge up front, Suarez won't waste so much possession as he'll have an attacking team mate that is worth passing to. I'm optomistic for the pair of them.
