In spite of that, it does not mean that other teams are not going to be interested in this player as well. If Barcelona were to actually transfer this player, then I believe that there will be a lot of teams that are very interested in his services.
My opinion is that he should actually think about moving out of Barcelona. The reason for this is that he is having difficulty adapting to Barcelona at the moment. In addition, there is no point being in a team which is not willing to give you the chance and instead they will give a better chance to a very old player. However, I do not believe that this is the main problem. It is pertinent to note that the main problem is the lack of confidence that the team has in De Jong.
The problem was Barcelona was not ready to let him go for anything less than what they were asking at the time. Yes, Barcelona also had some problems with the wage of the player. As far as I know, that is a big reason why he actually could not leave Barcelona. And that is why he came up with the reasons and say that he loves to play for Barcelona and that Barcelona is his dream team. But honestly, he wanted to leave Barcelona but he could not.
At that time a lot of teams had shown interest in this player. Manchester United was the most interested out of all. But now I don't know how many clubs are going to be interested in him. I am not going to be surprised if Manchester United still shows interest in him. But I also think that probably Liverpool is going to show some interest in this player now.
