Not every time, for me. There've been matches for Chelsea (including one this season, though I can't remember which off the top of my head), where he shows another gear entirely, takes the game by the scruff of the neck, and wins it almost single-handedly. The problem is that for every game like that there are three or four where he just seems to float around waiting for opportunities to dribble a bit. He doesn't have Mata's vision, which means the threat of him running at the defence is much more one-dimensional.
Schurrle is working hard to confirm everything I thought about him being too average for a club of Chelsea's ambitions.
