Even the best players on the planet can suffer from a lack of confidence sometimes, but it is so surprising to see it from the whole City team.
When they got thumped at home by Tottenham a few weeks ago, they at least tried to get back in the game and had a go at Spurs, but got undone on the counter.
This time, they offered next to nothing in attack after half-time.
Yes, they were ahead against United and I can understand teams protecting a lead sometimes and being a bit more pragmatic.
City might also have been thinking about what happened against Feyenoord, when they collapsed late on.
That negativity can stay with you, but not to this level.
They completely gave up possession for most of the second half, and this was not even against a good United side.
This was a United side who, apart from Diallo, were playing to contain City and for two thirds of the game did not have much penetration.
Yet City did not kill them off at 1-0 and, even worse, they did not even really get close to doing so.
That lack of creativity is a big problem for City at the moment. I know conceding goals is an issue for them as well but this is the first time under Pep that they are not looking like they are going to score either.
So, he has got two areas to address, and it looks like it is a huge task for him, especially because he has never had to deal with it before.
