Manchester United is said to be after de Ligt this summer. I hope it is true. Because it would be one of the best transfers to strengthen the defense line.
But would Bayern Munich like to let him go that easy? I don't think so.

He is a really young defender. Even if they think of selling him it would be for quite high amount of money. They bought him for around 70 million euros. I wouldn't expect them to sell without making a solid profit. Instead of spending 70-80 million euros on Jarrad Branthwaite, I believe they should prioritize de Ligt as a target. They really need to secure the line with a reliable defender.
Fans will definitely agree that Man Utd will really recruit de Ligt because he is a very great defender and in fact he is one of the best defenders that Bayern Munich has who can always be relied on in any competition and this can all be seen from Bayern Munich's current performance de Ligt suffered an injury and was absent from the match, Bayern Munich's performance became very bad looking very weak.
When de Ligt returned to appear with Bayern Munich, the performance of Bayern Munich's defense changed to become stronger.
The problem is that it is difficult to bring in de Ligt because he is still very reliable at Bayern Munich even though there is still Joshua Kimmich but de Ligt is one of the complementary defensive forces who always works with Joshua Kimmich and Bayern Munich really understands that losing de Ligt will make Joshua Kimmich less Their performance decreased because these two players often worked together to defend Bayern Munich's defense.
Maybe Man Utd could get this player if they made an offer of more than 70 million and Bayern Munich could consider it again.
