De Jong is playing very well right now. I think the reason why he didn't leave Barca was because of his love. This could be an expression of his love for Barcelona. Also, if he goes to Manchester United at this point, it will take him a long time to adapt and there are doubts whether he can play in the first XI. These are my personal opinions.
I agree that De Jong has love for the club and that will be the fundamental reason why he decided not to leave in the summer, he wants to play for the club but wants his wages owed to be paid, in my opinion it was a wise opinion to stay back at the club where he already build a fan base and good relationship with the players and coaching staff already. THere he feels at home and will play better.
De Jong didn't go to Manchester United because of any love for Barcelona. There is nothing like love, at that De Jong did was for himself and his interest. He felt that he needs to play champions league football to be more recognised in football and another thing is Barcelona technically held him back with buying off stories that Manchester United will pay. He is a good player and he is having
In the transfer process, the players themselves play an important role. As happened to Frenkie de Jong where Barcelona and Man United had reached
an agreement on a price, but because De Jong is still happy playing for Barcelona, finally De Jong refused to move to Man United. Therefore,
until the transfer market closed, De Jong still remained in Barcelona, because both Barcelona and Man United failed to persuade De Jong to move.
After all, De Jong's contribution to Barcelona is quite good, so it's a distinct advantage that Barcelona actually has a player like Frenkie de Jong.
And also Man United have got Casemiro, so De Jong doesn't need to leave Barcelona. I am very happy if De Jong can finish his contract at Barcelona,
I am sure De Jong will help Barcelona win trophies this season.
