The future of Ajax's young stars: Barcelona, Atletico, Bayern... Eredivise Half of Europe competing for the youngsters that toppled Real Madrid

Ajax's spectacular 4-1 triumph over Real Madrid in the Champions League has bumped up the price of Erik ten Hag's young starlets.

Their awe-inspiring performance helped the Dutch side book their place in the quarter-finals of the competition and as a result, they are sought after by many of Europe's elite.

Frenkie De Jong is the first one who has sealed a move away from the Dutch club.

He officially signed for Barcelona, who paid 75 million euros and 11 million in add-ons for him on January 23 and he will join up with his new teammates on July 1.

Barcelona wanted to snap him up after they heard PSG were also interested in securing his services. The youngster has signed a deal that will keep him at the club until at least 2024.

Another player whose name is currently on everybody's lips and not least those at Barcelona is Matthijs de Ligt.

President Josep Maria Bartomeu has already publicly declared his interest in the player.

"His name is definitely on the table," he during an interview with SER Catalunya. "When there is significant talent out there, we always take note and he is someone that we will continue to keep tabs on.

"In De Jong's case, we had to act fast because we knew that there were many other suitors who were vying for his signature."

Atletico Madrid are also interested in signing the young centre back and would use the money they are set to receive from the sale of Lucas Hernandez to Bayern Munich.

Nicolas Tagliafico is another player who is on Diego Simeone's radar and has been since February 2.

Simeone even personally contacted the player several weeks back to let him know that he would love to see him in an Atletico Madrid shirt.

"If Simeone has spotted me and is interested in signing me, it must mean that I am doing something right," Tagliafico said.

"For now, I am thinking about my future at Ajax. We are still in three competitions and I need to focus all of my efforts on that."

Bayern Munich are tracking another Ajax academy player, Dutch born Moroccan international Hakim Ziyech, who has been performing excellently of late.

The German club has already put the feelers out and has contacted Ajax to discuss a deal for the player who is valued at 35 million euros.

The 25-year-old, who has two more years left on his current deal, has 18 goals and 25 assists to his name so far this season in 35 matches.

Former Valencia player and current scout for the club, Vicente Rodriquez has made a number of trips to watch Ajax over the last few weeks.

He has his eye on Noussair Mazraoui and is keen to follow his development. The 21-year-old right back has had a swashbuckling campaign so far and is being tracked by Valencia.

The youngster is an exciting prospect who is as assured in his defensive duties as he is going forward and has chipped in with some important goals in the Champions League.

Ajax stopper, Andre Onana, has on various occasions voiced his opinion on what a dream it would be for him to one day become a Barcelona player and he is keeping an eye on the situation at the club with regard to the future of Jasper Cillessen.

Despite only being 22 years of age, he is now considered one of the best goalkeepers in Europe and is attracting a lot of attention for the big clubs.

Having said that, for now he is only interested in continuing his development at the Dutch club.

Even Ajax sporting director Marc Overmars, the man partly responsible for the club's excellent youth development has been attracting attention from several clubs across Europe.

His former side Arsenal were said to be interested in bringing him back to London but he politely declined saying that he is happy where he is.

In his place, the Gunners have signed Unai Emery's close friend Monchi on a three-year deal.
