If we get Mathieu indeed, then the Vertonghen-deal is off imho. Vertonghen offers the same capabilities as Mathieu (can play CB and LB), doesn't fit the profile that we're looking for I think: young RCB that can also play RB.
Has Schar already played RB before too?
Ya, it's dead for Vertonghen.
It's not as if it even started to be honest. As pointed by many people here, dealing with Levy is a pain.
To Levy, everyone can be sold for the price he thinks is right. That does mean asking other clubs to overpay by a lot.
He would never have sold Vertonghen for 20M given how the current market is. Try 40M and maybe he would listen, and even that's not sure.
