This was a very odd performance from Manchester United.
Their performance is always odd and unpredictable in this season.
They basically couldnt do anything in that match. Even the goal that is on the board against their name was not scored by a Manchester United player.
There was no coordination between Manchester United's attack and its defense. Well well well, was Aston Villa not in the relegation zone prior to this match?
Ronaldo played this match as a captain but he had another bad match and Manchester United wasted one great chance to join the top four of Premier League. Ronaldo will likely to have his last World Cup and simply said, his preparation for it is too bad.
Manchester United are in a decent position on the table, but the biggest problem is that they are very inconsistent. They will be unable to finish in the top four for as long as they are unable to be consistent with their scoring, so they will not have any chance of finishing in the top four in the near future.
Ten Hag only has a few months in Premier League and he needs more time. At least, I think he has done good jobs for Manchester United and gradually to find good formation for their players. Furthermore, he needs more good players to replace bad players in the current squad. In the winter transfer, in January 2023, I think Manchester United should buy a good striker. Ten Hag can not force Maguire to play at the striker position and get too many goals from that central defender.
I think Ten Hag should look for a right wing striker and a central midfielder to support Ronaldo's game, he is like a dragon playing with worms if Ten Hag still has hopes for Ronaldo. Of course it will not be easy for Ronaldo to bring his team as it used to be when he was young considering that his current age of 37 years will certainly greatly affect his playing performance, Manchester United's management may prepare funds to bring in new players who are more competent and potential in every part of Manchester's formation. United, as you said "Manchester United have to bring in new players" or even change the coach.
