I don't think thats to do with intelligence though. I just think its a lack of understanding with the players he's playing with. Case in point, I slated him on here for West Broms second, because he should have dropped off when Jones went to challenge, but I don't think thats because he's not intelligent, just a lack of understanding that Jones is an idiot and would go to challenge for that ball.
I think he reads the game quite well, which is pretty much the only criteria of being 'intelligent' I really care about, he doesn't seem to take unnecessary risks with his passing and if he can form a partnership with anyone you'll see the decision making improve.
I respect you're actually basing your opinion on a tangible observation on what he's doing on the pitch though. Far too many posts in here have people writing him off with no justification.
