He's a good player, no doubt, and could become a top player - but for me it's not worth it. We've got enough young talent as is; we don't need to splash out ridiculous money on this guy.
He's English, young, at Spurs & in form. That makes him at the peak of his value & would cost money that could be far better invested.
Don't believe he improves our first 11 either, he'd be competing with Silva/De Bruyne in the formation we've been playing, no chance he's better than them currently. A replacement for Silva in a few years could work well (different pro's/con's), but can't see us splashing out what it would cost & not playing him.
Would be very surprised if this was genuine or even got close to happening, for me there are far too many obstructions.
