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.
