I am surprised by your statement, you're usually good with your analysis of the football.
We have had 2 offside goals and each time, Rashford was at fault but the movement and ball passing was crisp and smart, breaking lines with triangles.
The Rashford goal was individual brilliance but the construction needed Bruno.
What made us not look good in the last game was the fact that we had a lot of passes that were missed. And as a result, we give away possession, helping the opposition. I can only consider that as being a lack of concentration due to loss of focus and fitness. When we are match fit, our players won't make those mistakes. We know that because we've seen the goals, and sequences of brilliance they are capable of having, including the goals ruled off for offside. Can we improve? Yes, we definitely need the ability to change and update the team when some of the players are out of form. But you won't see Pogba slip and miss a pass often... and that was all over the pitch across almost all players.
I do think there are areas of improvements. But Ole knows them and our focus right now should be winning games ugly, until match fitness is top notch. That's at least the whole month of October. One hope we can have is that if our match fitness peaks later, maybe we will have less issues with the end of the season relative to the other teams.
