Said it soon as we were linked with him. He's a very visual sort of player. By that, I mean he stands out when he plays well because his tackles and clearances are thunderous and aggressive. On the flip side, because of this aggression, he is prone to mistakes.
He became a £30m player off the back of a good goal scoring season (for a centre back) and some eye catching aggressive performances in some of the bigger games. Before last season he was struggling to establish himself in Europe.
Don't get me wrong, he is decent and I like him but we have spent an awful lot of money on 'flavour of the month' types of players or on players who have had one good season in a popular league when I'd like to think we have a scouting system that should enable us to pick these players up before they have their 'break out season'. It's a model that Atletico, Dortmund and Valencia follow and it saves them a lot of money.
I've gone off track but it's a long winded way of saying, we should have stuck with Mangala and Denayer and spent the 30m on a centre midfielder who allows us to exercise much greater control of a match thereby lessoning the number of ocassions our back four get exposed in breakaway situations.
