If I'm completely honest, I don't care about the performance too much, as long as we win. 3 points is more important than playing free flowing football and looking good at this point in the season.
I'm not judging Mourinho until next season when he's had a chance to put his marker on the squad, have more time with them and work on areas that need working on. He's never taken a job mid-season, and not only has he done that this season, but he's also had to deal with a pandemic disturbing the season, losing his 2 best players and then having a shortened preseason due to this season being disrupted.
