I've only been following him since he joined Albion, so I haven't got a set for him yet. He's become a hot property in the Championship over the past two years or so, and quite rightly so. To tell you the truth, I haven't watched him as intently as I have players like Ince and Zaha, so I can only really describe him in very vague terms. In fairness to him, he's up there with the best in the Championship when it comes to technical ability - he has this real "continental" style so to speak, in the sense that he has the verve and flair you'd typically associate with players from abroad - but I've been preoccupied with working on player's who've really come in to their own this season, this Championship seasons stand out players, as it were.
No concrete values right now since, as I said, I haven't paid as much attention to him as I have with others, but what I will say is, he's far better technically than these stats give him credit for, and he's got excellent control. He'd sit nicely on an 83 for DA, and he could do with some skill cards as well - very proficient when it comes to heel chops and such, which I suppose is aided somewhat by his nice turning circle. Also likes to take defenders on and beat them with little shimmies and step overs, so that's something to note.
I know for sure he needs a higher ACC, he really does burn past most Championship fullbacks. Also, my memory's sketchy, but iirc he sometimes plays as an attacking midfielder, although I'm not quite sure whether he's actually deployed there, or if that's a result of his drifting inwards.
Apologies for only describing him in vague strokes, I do plan on following him more closely next season (unless of course he makes the step up to the Premiership, which is becoming increasingly likely). Definitely a player to watch out for.
