My new worry about us signing Higuain is that we might now face competition from Chelsea and Man City for his signature, what with them also needing a new forward and also both not getting any closer to signing Cavani. City especially worry me because they have the money and also have a few Argentina players in their squad.
I doubt Chelsea are a threat, because Mourinho is the guy that didn't play him at Real.
Man City maybe, but they still have Dzeko and Aguero.
