I'm clearly going to get drummed out of town for this one, but - he was absolutely terrible last night. And he has been for ages.
Of course he's been utterly class for us. But at the moment he's getting the basics wrong - simple control and passing is off. And his insistence on always having to go for the killer ball, every. single. time. Feels really immature to me, and it's costing us possession and control in big games.
He did calm down a bit when Pogba came on. I suspect that when he's our only creative outlet then he feels too much pressure to make the difference and force things.
I wouldn't just say it's the creative issue as the forwards we have don't do their jobs in terms of forward runs and positioning i.e. they are never in positions to strike, in the literal sense of the word - tap-in's, near post runs, far post runs, zig-zagging or dummy runs, they do none of it, so more onus is then put on Bruno's shoulders to create or affect play himself or find players who are in poor positions to progress the play.
Pogba coming on alleviated a lot of pressure and meant Bruno could run away from the ball and look for pockets of space and probably take more stock of his surroundings, but actual runners ahead of him changes his mindset equally as much and gives him options outside of hitting that runner (the by-product of one good run is others following in around it) with a pass. He can't switch play much without Cavani in the team, for example, and that's because literally nobody else in our attack has a clue how to make concerted dummy runs or think, before setting off on a run, how what they do causes a chain reaction.
Bruno's a hybrid midfielder/forward, and I think it shows in how he thinks and plays his game - he always plays in a do-or-die manner, but I think his ideas and pass selections improve significantly when those around him give him something to think about in his own usage of the ball.
He should slow down and play a more considered game, but there's no evidence he can do that or wants to as he's been the same since he got here, just that he's effective in what he does more than he isn't which means he's a success.
Better users of the ball behind him and better runners off (and on) the ball ahead of him, and he's in his element. Without that, he'll try too hard to be the hero sometimes to the detriment(knackering himself out) of himself and others (chasing around when his errant passes lead to marauding counters back up the pitch).
