People all ready trying to play down how good the lad is though?
Yes, he's made mistakes. In my opinion no more or less than many of the 'so called' top defenders.
He gets slated for being a bad defender yet in the first half of last season was our best all-round player and defender, and that only stopped when he hit a shaky spell of form (as a 21-year-old in his second full season in the PL it's probably to be expected).
The knives were out from then on in and tbh for the Evertonians who don't want him here we're getting exactly what we deserve by selling him.
I don't want him to go, I want us to build a team around him, but ultimately he wants to leave for bigger (and, let's face it, probably better - at least in the short term) things, and we'll get a handsome fee for him which can be used to re-invest back into the squad.
