Pato Return to Milan This Summer?

There's rumours going around that Pato maybe be returning to Milan this summer.  I heard these rumours from @TheMilanGuy on Twitter(I highly suggest you follow him), who never reports from unreliable sources.  I love Alexandre Pato, but I'm not sure if he's going to come back or if it'd be a good idea.  He had a great season with Corinthians and managed to stay relatively healthy as well.  I don't see why the Corinthians would let him go, considering he was one of their top goal scorers and he just recently moved there in January.  Also, would he even fit into Milan's current squad?  For me personally, I'd only want Pato back if he, Balotelli and El Shaarawy would all start and work well together and I'm just not sure if that's possible.  Balotelli should definitely play in the middle of a 3 forward attack and SES should definitely play on the left wing, but Pato isn't much of a winger.  Although, there is a formation that could work.  As many people probably don't know,  Stephen El Shaarawy is naturally a central forward and could be very effective as a trequartista.  By putting him in the #10 spot and pairing Balotelli and Pato together up top, that could work extremely well.  Adding onto that, Boateng, Montolivo and whoever else Milan signs for the midfield, instantly Milan have an extremely strong squad.  That scenario is only going to happen with the right coach, and Allegri would definitely not do that as he has no tacticle IQ at all to figure that out.  As I'm typing this blog right now, the more and more I want Pato to come back and want the formation to happen.  Ideally, a 4-4-2 (diamond) would probably fit Milan best if Pato came back.  Any midfield formation that would put El Shaarawy behind the two strikers would work.  I think it would be a great signing not only for Milan, but also for Pato.  His first stint at Milan was just bombarded by injuries every time he took a step outside his home and now that he was able to go back to Brazil to put his career back on track, I think he can come back to Milan and be absolutely excellent.  Berlusconi also really has a liking for Pato.  I know Pato would love to come back to Milan, but I don't think the Corinthians are going to make it an easy transfer.  We'll just have to wait and see, also, it really depends on who Milan's manager will be for next season.
