If we fail on Higuain, Tevez would be a great back up plan.
His salary though would be a huge problem, we need to sell a lot of players first, to help the wage front.
Tough luck with that, as it happens to be Marotta's greatest weakness... he cant buy quantity and he is forced to buy quantity, this multiplies the problem when we need to make space and whats worse, he cant seel a player for a decent price, not even when his life depends on that. The EPL higher standards go beyond Serie A capabilities.
Otherwise, he could be available for a decent transfer sum and he would even accept to join the champions of Italy and a rising power in CL, but i really doubt that he will choose glory over $...
