There will probably be a plethora of world class strikers moving this summer and we need to get one of them.
Cavani will almost certainly move as will Falcao, Suarez will move too and I fully expect Rooney to move as Baconface will want to shaft him. Lewandoski will quite possibly move and there could be others. Neymar too might move or at least agree a 2015 deal which may hold back a club from signing, behind these we could easily see Villa, Higuain, possibly Ronaldo move too!
We obviously wont touch Rooney now and we will have to compete with Real, Bayern and Chelsea but there is a world class player to be had. Lets say Neymar to barca happens, that Falcao goes to Chelsea, Lewandoski to Bayern and Cavani to Madrid - even then we could still have a good go for getting Suarez and Villa to add to Tevez and Aguero which would hardly be the end of the world.
I think a lot will happen and we need to be talking to the 4 or 5 world class available players so that if we do miss out to Madrid or bayern (hardly unlikely) in going for say Cavani and Neymar or our first two choices we can still sign a top player.
BTW I would be loathe to sign Suarez as I think he's a dick but just highlighting the talent available!
