If we consider the results that Manchester United got in their second season with Erik ten Hag, even though they experienced a decline from the first season. But in reality, they still managed to compete at least in the middle of the standings, and they still managed to get trophies even though they played against a strong team like Manchester City. Thus, I personally still quite confident that Erik ten Hag is still able to keep Manchester United stable in the middle of the standings to the top of the standings.
Manchester United got lucky last season and they won a trophy over Manchester city as they were underrated by Pep gaurdiola. That trophy wasn't his focus or he won't had allowed Manchester United to win him but praises has to be given to Erik ten Hag as he manages to get united into the Europa league despite them to having a very good season. Infact United were poor all throughout last season although they might improve this season as they are signing good players. Manchester United are capable of winning the Europa league without any doubt as there aren't any big teams in the Europa league, every club there is an average team base on their current form.
