I always thought he's over-criticised. Quality player, imo, and he's been so for the last couple of years now. Will only get better.
Cast your mind back to the 3 goals he scored past us (in two separate games; 4-0 in the LC and the 4-4) during the 09/10 season. Three times he went one-on-one with Krul and 3 times he finished it excellently. Not to mention the 3 good finishs last night, of course.
