So I think the absence of one or even two key players on the pitch has a coordinated effect on the result, maybe that's why MU players have become worse. Ten Hag's problem that can be blamed on him is that he can't find a competent replacement for an injured player, but that's the most I could charge him with..
Ten Hag can only utilize and maximize the players currently available, he cannot find replacements for injured players and add them to the main squad because the transfer window has not yet opened. This can only be done in January, now Ten Hag must be smart in rotating players and determining the best options in dealing with the storm of injuries. United are now missing five defenders, as a result they are conceding more goals than they are scoring.
Previously, The Red Devils lost surprisingly to Galatasaray at Old Trafford on the second matchday of the UCL group phase, furthermore United closest match will be hosting Brentford in the EPL competition. United should be able to secure full points in this match, because Brentford is a weak club and has only won once this season in the EPL. However, if it fails again, I think it's time for United management to end Ten Hag's tenure a little sooner.
I wasn't referring to the transfer window, I was referring to the players in the team. Maybe they have a player who hasn't played for MU, or has played very little, but is playing well and can help his team at the moment. That's what I mean, if there is such a player and Ten Hag doesn't use him, then I don't know what arguments can be made in his defence
