I've seen him live (on tv obviously) quite a bit mate as they get shown on tv here all the time, i dont think the consistency id down to him not wanting to play, being lazy etc (although their is a bit of that in their), its mainly just the type of player he is, think paulo wanchope for an example of what i mean by that, he is naturally a inconsistent player if that makes sense, and at 26/27 its hard to get a player away from something which is just part of what they are as a person and player
Dont be fooled into thinking he's a technically good player mate, he definitely isn't, what he is is very very fast and he beats people by knocking the ball past and winning the race to it, works a lot better in a weaker league like here in russia than it will do in the prem, those type of players are quickly worked out in the higher leagues
