Suarez should still be first port of call as he is the best striker in the league, however I can't see us getting him until the summer and by that time madrid will bid as well, only hope will be that thye get falcao off monaco and leave us to suarez. Failing that we should try to convince lewandoski, though he look a bit like a the sort of player we produce, someone who excels in his current team but fails to translate it out to other teams.
Bender and Reus should also be high on the shopping list as arteta will need to be phased out in the next couple of years, and I can see Walcott going off on one o another team or demanding a shedload of cash this summer to sign another deal.
