Manchester United didn't do well in the beginning of the season last year and they are doing the same this season. In the last two games they lost unexpectedly vs Crystal Palace in EPL and Galatasaray in Champions League. Defensive errors are unforgivable in such highly intense competitions and injuries couldn't be an excuse there.
Their next two games aren't that hard before returning again in Champions League and facing just next Manchester City. I am not very optimistic about them in Champions League nor vs City.
However, Man United's performance at the start of this season was quite disappointing. They may not be a bad club, but, they sometimes play very badly. Even when they have had good opportunities, they have not been able to execute them well enough. Some of Man United's failures in the previous few matches were also quite surprising, and Ten Hag was someone who was quite responsible for that. Because after all, sometimes making decisions during a match is quite surprising and makes you ask a lot of questions. Well, not only that, the Man United players were also not as optimal as last season.
After yesterday's defeat against Crystal Palace, next week they should be able to do much better and win against Brentford. Even though we know that Brentford is sometimes quite troublesome.
Unfortunately, they may also still be devastated, especially with their defeat in the UCL yesterday against Galatasaray, they haven't even got a point in the UCL.
