I just rewatched the Spurs goal. His punch in itself wasn't actually that bad. He theoretically punched it away from the danger area. The main issue was that he should've caught the ball. Having said that, the conditions were terrible for a keeper trying to stop crosses.
Overall it was an ok game for him. Made a couple of quality of saves but also made a mistake that cost us the goal.
It was more than a couple of quality saves, DDG and Rio pulled off a few moves that kept us in the game, it could have been 3-1 to Spurs at one point which is why I can't blame DDG for that result.
