Ajax are set to offer Nicolai Boilesen a new deal in an effort to ward off interest from Manchester United, according to reports.
Spanish giants Barcelona are also said to be interested in the player, according to talkSPORT, with the teenager being monitored by both clubs throughout the previous season.
Boilesen spent time with Manchester United back in 2009, but opted for a move to Ajax from Brondby rather than a permanent switch to Old Trafford.
Contracted at the Amsterdam Arena until 2013, the Godenzonen are hoping to convince the player that his future remains in Holland rather than a big money switch to either of last season's Champions League finalists.
"He deserves a new contract. It ends in 2013 but it's good to add more years. We want him here - not anywhere else," said a source close to the club.
Sir Alex Ferguson has already strengthened in the central defensive region this summer, bringing Phil Jones to Manchester United for a fee reported to be in the region of £20 million.
Jones joins England U21 compatriot Chris Smalling, senior international Rio Ferdinand and club captain Nemanja Vidic at Manchester United, whilst French starlet Raphael Varane is also being linked with a move to the Red Devils.
A move for Boilesen would again prove Ferguson's willingness to invest in youth at Manchester United, with the Scot looking to build a lasting legacy for years to come at the club.
