I think the penalty decision could have gone either way. But Schweinsteiger can't have any complaints, there was no need for him to be throwing out his hand like that. From the referee's position it probably looked hand-to-ball.
As others have said, Pogba needs to stand up and be counted, he's been very poor so far in this game. Although, he's probably wasted playing in the pivot, it doesn't look his most comfortable role ?
