This doesn't tell the whole story. Most of the possession that Man City had was passing between their midfielders in their own half or near the halfway line. It wasn't this blitzing display that some people seem to be making out.
Our team press is an issue; we are not organised at all and it does make the job harder. This lack of an organised press will always put us in this position. We can win by countering, but it doesn't work if your forwards play like they did yesterday.
For me, you can only get away with a disorganised press if your counter attacks are effective. And yesterday, Rashford, Martial, and Fernandes were poor and provided no outlet. A disorganised press has a massive impact on a player's performance as, if it is done well, it makes their job much easier.
If you combine most of Man City's play happening near the halfway line and us not really being a pressing team, the culminating result is a low number of tackles. It isn't really a surprise. I don't think defensively, Mctominay and Fred were an issue at all as Man City weren't this all domineering team. They had a lot of possession, but their threat was actually pretty low. Their best chances came from mistakes in the defence and a very good goal from Fernandinho (poor header by Wan Bissaka beforehand). They didn't come through the centre of midfield.
I would say in possession, though, that Mctominay has been a problem. He is completing a ridiculously low number of passes per game for a midfielder. He almost makes half the passes per game that Fred makes, which is making it difficult for us to sustain possession for long periods. I do think if he doesn't pick it up, we definitely need to look for an alternative who will make themselves available more. Mctominay hides away far too much or is just bad at positioning.
