If we are seriously close to agreeing a deal for Higuain, then, this isn't happening anyway. The whole Wenger wants to link Rooney with Higuain story-line is rubbish from Daily Mail to link Rooney to Arsenal.
A primary motivation for Higuain to leave Madrid is the fact that he is not the main man there and the same for Rooney is the fact that he is being made to play as attacking midfielder. So, why would they agree to come and risk facing exactly the same problems?
And we haven't even started about how unrealistic Rooney's wage is for us or us buying two 20 mill/100-200k wages players for the same position is.
