I'm aware we signed these players, it's just as you even say yourself, not players of his age. If De Zerbi thinks he's up to it then that's good enough for me, plus left sided CBs to tend to carry a premium.
The price quoted is not ridiculous for an established international with Champions...
I think in between all the wonderkids we sign (which is a great policy for me) we do need the odd ready made player like this one. Especially as we are unlikely to be able to sign Colwill. Make it happen Tony!
