Ajax have reportedly set an asking price for highly-rated duo Matthijs de Ligt and Frenkie de Jong, according to Mundo Deportivo.
The Amsterdam side will not accept anything short of £124million for the pair, who are wanted by Juventus and Manchester City, however, it is understood Barcelona lead the way for their signatures.
Ajax expect bids for the duo in the upcoming window despite De Jong being in contract until 2022, while De Ligt's current deal runs out a year earlier.
The club are understood to value de Jong at around £66.3m and de Ligt roughly £57.5m.
De Ligt, who is only 19, is regarded as the best young centre-back in football at the moment and has been a key figure for Ajax in their progression to the Champions League last 16 for the first time in 13 years, and Holland's progression to the Nations League finals next year.
While de Jong, who is also regarded as one of the best
young players in the world in his position, has been equally as important for
club and country so far this season.
Ajax and Barcelona legend Ronaldo de Boer, who is now a youth coach at the Dutch side, has urged the young players to join Barcelona.
"I advise them to sign for Barcelona, or if not, for Pep (Guardiola's) Manchester City," the former Rangers midfielder said. "Ajax's style is the same as Barca's they could adapt quickly. I would also advise them to go to Barcelona because the club is in my heart."
The 48-year-old also said the players should pick a team that suits their style and not for the money.
"One million more or less doesn't matter. The important thing is that they go to a team that fits their style. They have a lot of quality and there are many clubs interested.
"Barca have to renew their team in the coming years because if they don't they will have problems like Bayern. It is better to sign young players now and to get them ready for when they have to start games."
The Catalan club are 7/2 to sign the defender in the January transfer window, while de Jong is 10/1 to move to the La Liga champions.
Manchester City are 5/4 favourites for the 21-year-old midfielder and Juventus are 23/10 to sign the defender.
