So, that is the problem for Man United because they have to compete with Bayern Munich to be able to recruit this player. Apart from that, Bayern Munich will not give up on making an offer to Leverkusen at a higher price, while Manchester United doesn't seem to be able to make a higher offer than Bayern Munich.
Until now there has been no decision regarding either of them, but I really hope that Man United can finally recruit these player considering that the club really needs a defender.

No! This is not a problem for Manchester United, they have no interest in the player, they're only making possible inquires about the player if he'll suit them squad or whatever.
Secondly, they're in no Competition with Bayern Munich, nor do they have such intentions to go head for head with Bayern Munich for Jonathan Tah. It's simply clear, Bayern Munich wants Jonathan Tah and he also wants them. Not even Bayern Leverkusen would be able to stop him from moving.
Manchester United has just signed a new defender who will definitely last the club a long time. He is young but still class at his age. Leny Yoro is the name, he has also just been announced recently as a Manchester United player. Asides Leny Yoro, Manchester United are not giving up on the name De Ligt, who Erik Ten Hag wants clearly. There's no issues with the personal terms agreement but Manchester United and Bayern Munich are yet to have agreement on what valuations to sell him.
The only defender that Manchester United focuses on now is De Ligt and we all know it is just a matter of time if not Manchester United signs him, Manchester United is not in any competition with Bayern Munich, Bayern Munich is very clear that De Ligt wants to leave Bayern Munich to join Manchester United, Manchester United want De light because he is a type of defender that Manchester United wants, although Manchester United have sign Yoro and they have Lisandro Martinez but they need another defender that is older than Yoro, Yoro is just a young player and he needs time to learn some things before starting having a minute to play for United.
De Ligt's signing might take time but I’m very sure that Manchester United will get him before the league starts, Let's be honest, if Manchester United doesn’t play very well with the squad they are about to gather now it will be a disgrace because Manchester United is the team that is buying players up and down, although we will not be expecting much from them because they need a time to build up their squad but at least they should be able to play well against some teams and able to win a trophy and qualify for the champion league.
