Who says we have not replaced Song? Who needs Biglia? Where would he play?
Only those fresh from Mars can say we have not replaced Song. Arteta is a faaaaar better holding midfielder than the Cameroonian, no doubt. Arsenal don't need Biglia at all. Rosicky, Wilshere, Coquelin, Frimpong are yet to stamp their authority on the team this season with some injured and others well behind the pecking order. Where would Biglia play?
Besides, he was linked to Norwich in the closing stages of the transfer window, not Arsenal. We don't need him, as Wenger has also publicly rejected links with him
I hate the habit of the media linking players to us when we actually are not interested in them, so that when they end up going elsewhere, they conclude that we've been beaten to their signature. I don't think Boca would beat Arsenal to any player if we are genuinely interested in them, really!
