His indecision when he has a moment to think.
It's almost as if when he gives himself just enough time to second guess he does and guesses wrong.
I seem to remember him running straight through about 3 or 4 Chelsea players, last season, get clear, then completely fluff it.
I'll hazard a guess...
Would rather see someone break the mental block Solly has when he gets into the final third of the pitch.
He's so much better a player than his cold hard stats would suggest.
