Genuinely thought last time I saw him at Derby, he was MILES off the level. 
Thought he was one of our better players on Sunday, even though Villa had stepped off the gas a bit, was very bright. Not sure if my assessment at Derby is a reflection now - perhaps not miles away, not quite ready for regular starts, but on option of the bench.
Perhaps he may be a casualty of not ever being comfortable in games, meaning he cant get any minutes that aren't really under any pressure.
