Frenkie de Jong had recently had a relationship with Barcelona. In the last season, Frenkie de Jong had an effective role in this team and he was the reason for Barcelona to have good performance in many games.
But since he got injured many times during this season he was mostly out of the squad and this is a reason for Barcelona to be disappointed about Frenkie de Jong.
He had some offers from Manchester United during last summer but he decided to stay in Barcelona but now it seems Bayern Munich is trying to use the chance and they want to hire this player since Barcelona is probably not going to keep him for a longer time anymore.
He helped Barcelona a lot, but because of some undesirable problems such as injuries that befell him, it made him miss several matches and that made him unable to help Barcelona optimally. But I can't blame him, because injuries experienced by players are actually things that the players themselves don't want, but no one can know when it will happen to them.
If Barcelona wants to sell Frenki De Jong then they can take advantage of it by setting a high price. Especially if there are several teams that are very interested in bringing him in, such as Manchester United, who have actually heard the news that they are interested in De Jong for a long time, but Barcelona are keeping him. Now is an opportunity for Manchester United if they are still interested in this player, but they also have to move quickly because they are not the only ones interested in the player, there are still several big teams who are also eyeing him.
