No he didn't mate. He was signed at the start of 05/06.
Banega was first linked in the Moutinho summer (2008) - we ended up with Felli. He was linked again the year after.
Billy was signed in 2009 when we sold Lescott, as you said. Distin, Heitinga and somebody else (can't remember who) arrived on deadline day that summer.
