If Ten Hag is still given the opportunity until his contract expires, I think he will recruit new players in defense. he will struggle to mold United's defensive line which has been quite chaotic this season.
Ten Hag definitely knows the weaknesses of his squad. and he will only use them until the transfer window opens. If he gets support from the club, he will definitely bring in several players to strengthen the squad. even though we know not everything will be as successful as expected.
United are still in trouble, but we don't know that from the coach or the players. last season they also performed quite well after half the season. However, Ten Hag doesn't want to get pressure from fans. maybe he should be nicer to the players and start putting together a solid team.
He tried last season but somehow I didn't really like their signings in defense and some of the other decisions that were made there like bringing back Evans as an alternative in defense and trying to keep Maguire even though there were offers that were detrimental but with Maguire's performance in the previous few seasons I think it could be a good choice with the value that West Ham offered.
At the moment they still have to try and find some players and that's something that has to happen because at the end of the day even if their attack is always scoring goals it won't mean much if their defense is weak and always conceding goals.
