He's 6 months into a new 6 year contract he signed in may, after only signing a five year deal when he signed in september just last year.
Therefore we can assume he is very well regarded and southampton knew that very soon clubs would come sniffing and probably built have some clauses built in his contract.
I think they bought him for about £13m.
He looks the part on the little I have seen of him but didn't he partner Denayer at Celtic? Maybe if Denayer had been bought by a club giving him regular starts and not chucked into the midfield of a defensive side managed by a complete fucking nupty, we'd be seeing him have a blinding few games and thinking why did we do letting him go?
As it is, from the BBC, "Denayer played just seven passes despite playing the full match in midfield, while Liverpool captain Jordan Henderson played 128".
Personally, i'd rather we get 2 new full backs.
