From that it certainly seems we made an offer.
Basically Newcastle must have been offering him far more cash, 'my heart told me to go to newcastle' my bollox. His wallet told him.
Maybe being at Chelsea where we're seen as one of their main rivals recently made the move difficult too, but basically I think it comes down to cash and the fact he knows he'll be an automatic starter at Newcastle whereas he'll be rotated here (but I still imagine he'd have got more games here than Chelsea). His loss.
