He really isn't. He's a good player., but he's far too inconsistent to be "very good". He had a peak season during 14/15, at which point Pardew started spouting he was worth £25m and so on...presumably never expecting to get that, merely trying to put clubs off. He certainly didn't have a season last year which would justify an increase in value. Everton have just publicly talked themselves into overspending - which is going to be interesting given their 'ITK' anticipates 7 new arrivals (inc. Bolasie). Not that he won't improve their squad, because he will.
