Mascherano is a first team material... He came to us. So is Alexis, so is Fabregas and so is Ibi
If we do come to the point where the boy really impressed the coach and we decide to bid for him, I don't think he will refuse to come... Chelsea winning or not. Only we need to still be a winning machine
Mascherano moved for family reasons. Hence the fin. compromise from his end. He also saw no threat to his starting place for Argentina by accepting a squad role here. It has worked for him, mostly.
Cesc was disillusioned and wanted a move back to further his career. If Arsenal weren't such failure in his time there, his transfer would be delayed or not materialised even. La Masia would 've provided us. But now that he's here, he'll cement a starting place soon enough. Xavi(given his age and fitness) 'll be used conservatively.
Alexis takes Villa's place. Ibi's future, unfortunately, doesn't belong here.
In short, Alexis, Cesc 'll be regulars in the near future while Masch is just happy keeping his wife happy.
Romeu's case is diff. Busi has the DM spot locked for years to come. Romeu with his talent might 've to play second fiddle for most of his career. Would that be fair for a young lad? He has expressed his desire to return, but anything can happen between now and then. Anyway, its all conjecture at this point.
Let's hope he fulfills his potential first.
