I thought she was good in the first half, think the VAR penalty incident knocked her confidence. She clearly didn't want to give it with the amount of time it took, although my view is she moved her hand to the ball and it was a penalty.
She didn't manage timewasting well at all. Not just the potential second caution, but there were other obvious cases that she didn't manage, the most obvious being when Spain spent ages setting up a corner only to then switch the taker with someone coming from a long distance away. That's a classic tactic and has to be a caution, I'd be expecting a Level 7 to be dealing with that let alone a FIFA referee. I'm going to be honest here, I don't think many FIFA referees would be giving a second caution for kicking the ball into the crowd, and certainly not in a World Cup final. The mistake Penso made was going to her pocket before realising who it was, better referees wouldn't make that mistake. And the English players missed a trick, if they had got around her she really wouldn't have had a lot of choice but to pull the second caution out.
