Great free kick and all, but I really think the goalkeeper should save that.
My view on this is pretty much that the goalkeeper needs to trust his wall all the time. Don't ever do the baby steps towards the wall gamble! If a player curls the ball perfectly over the wall and the goalkeeper can't get there then, fair enough, hold your hands up and congratulate the free kick taker for a perfectly executed piece of skill. However, this shot is at most a meter to the left of the goalkeeper, in his corner, and far from a rocket. Any goalkeeper worth his salt needs to save that IMO. I'd certainly have it down as a Cech error if he conceded that.
