Because maybe they came in with a good offer which made him think twice due to Spurs holding out on bidding ?
It's a big life changing decision, people can change their minds or get cold feet.
But he'd been "tapped up" mate apparently.
I'd buy that he maybe decided to see what numbers they'd throw his way, but he'd seen those, agreed to them and signed the contract.
You're telling me that in the space of a few hours, after being perfectly happy with those terms, that he'd decided to go back to 'Plan A' and sit it out at the last possible minute, with nothing acting as a trigger to do so whatsoever?
It's possible but... that's one hell of a stretch mate. I wonder what Spurs made in that scenario seeing Ross, their "tapped up" future superstar, rocking up to Chelsea for a medical this evening?
