There's been talk of him having an agreement with Spurs that if a Champions League club come in for him then he can go for a set fee although I obviously don't know if that's right.
As it is a top keeper would be worth more to us than he'd probably cost to buy from Spurs anyway. There's a tipping point for any player and the tipping point for a keeper - especially one who wants to go is likely to be less than outfield players. What would he go for - £25 million? Its worth every penny if you're filling a gap you need to fill.
And the big issue is this could all have been done by now anyway.
Do you think Lloris is not error prone? The guy had so many errors last season that I lost count. He isn't all that what is being made out at all. At least Romero was free.
