A young man is at the Barcelona Camp. If Frenkie is to deliver on his potential then Old United will be the place to go.
The 25-year-old is one of Barcelona's most saleable assets because of the club's financial constraints but he is not interested in leaving.
A broad agreement over a 65m euro fee, plus add-ons, has been agreed with Manchester United in a move that would re-unite the Netherlands international with the coach who got the best out of him in the run to the European Championship.
Through a period of upheaval, managerial changes and financial uncertainty, De Jong never hit the heights he was projected to.
Alan Feehely, editor of Football Espana, says that he will be remembered if he leaves this summer.
He has never settled. He has been there for three full seasons and has never dominated a game like Pedri has.
He failed to find a true position in the middle of the field. It will be one of the regrets if he leaves.
Before his move to Barcelona, Frenkie de Jong praised his coach's tactical approach, and he won a league and cup double under Ten Hag at Amsterdam.
After making his Eredivisie debut two days before his 18th birthday, De Jong was signed by the Dutch giants.
According to a former coach at the Amsterdam club, the most exciting young player he had worked with was theMidfielder, because of his good ball control and ability to engineer time and space.
He had to find the best role for De Jong to showcase his talent and make the forwards perform better.
He told Dutch TV that he wasn't a scorer. The player who supplies the team-mates who give the assists or who score goals is called the player who supplies the team.
Ten Hag has spoken about how he used De Jong in a system with "two number sixes" at Ajax, but he even had outings at centre-back, something Michael Statham, from Football Oranje, said did not work.
He says it was an experiment to get them to play on the ball. He got beaten for pace on the turn multiple times and was exposed as a result.
He was mostly used as a defensiveMidfielder by Ten Hag. He used him to make something happen.
He is a genius in the middle of the field. He tried to get the ball moving between the two center-backs. He was often used as an outlet by the goalie.
He would be on the edge of the area, not taking shots, but moving the ball on again, putting players into neat positions inside the box.
Ronald Koeman, the former national team boss, still regards the player highly, despite the fact that he got the best out of his countryman.
Dutch coach Ronald Koeman told Catalan radio this week that he was a great player for Barcelona and that the player told him he wanted to stay.
During recent international windows, current Dutch boss Louis van Gaal has talked up De Jong's talent, even though he was discouraged from moving to Manchester United at this stage in his career.
Frenkie is very important to me. According to a recent CIES Football Observatory study, Frenkie is worth 112 million.
The deal will represent a large chunk of Ten Hag's budget, but it will be less than that figure.
The departures of Paul Pogba, Juan Mata and Matic this summer have made it necessary for United to reinforce their midfield.
Feehely says Ten Hag's pursuit of the midfielder this summer shows how valuable he believes he will be to his United side, and that he witnessed De Jong at his best in Spain.
He isn't a Marco Verratti or Thiago Alcantara who catches the eye with their control and play of the ball.
He is more of a Xavi type player and makes the team tick. He doesn't have a lot of strength or speed but when it comes to regulating the game he is superb.
He will bring some sanity to a club that is pretty chaotic and chaotic in the middle of the field.
He needs absolute faith and experience in the middle of the park to thrive, but he doesn't have that at Barcelona.
He can receive the ball from deep and make those transitions in play, drawing players to him to bring that space and bring teams out of their shell.
He is always available to take the ball in tight areas, he can wriggle away, win a foul, dribble past players and then play that ball into someone else who is going to give an assist or a goal."
I don't think anyone in the world can do that better than him.
