Ajax director of football Marc Overmars has insisted the club will do everything possible to keep starlets Joel Veltman and Davy Klaassen at the club, reports the Express.
The duo have both been heavily linked with a move to the Premier League, with reports having suggested that the likes of Manchester United, Chelsea, Arsenal and Manchester City are tracking the duo.
Manchester United appear to be heavily interested in a move for centre-back Veltman, who has impressed this season.
Red Devils manager David Moyes looks set to bring in a number of players in the summer window and defence looks set to be a priority after club-captain Nemanja Vidic revealed that he will be departing the Old Trafford outfit.
Meanwhile, Arsenal were thought to be in pole position for the signature of Klaassen. The youngster is an attacking-central midfielder and would join a fine array of attacking talent at the Emirates if he was to move to north London.
However, ex-Arsenal star Overmars, has warned the Premier League's elite clubs off the signings of the duo.
The ex-Gunners star told reporters: "We are constantly working on a puzzle and every time you have it almost complete, it can fall apart, because a piece is snapped up.
"But I will lie in front of the gate when they come for Joel Veltman or Davy Klaassen.
"I love Ajax being attractive for a transfer, but these guys are not leaving here.
This news will come as a blow to the likes of Manchester United and Arsenal, as any deal for the duo now appears unlikely.
Overmars has insisted that Dutch club will soon start contract negotiations with the pair as he continued by saying: "We have the intention to break open the contracts, and then upgrade and extend."
Manchester United and Arsenal will now turn their attentions to this week's Premier League fixtures as the two sides go head-to-head at the Emirates.
Chelsea and Manchester City are both in action too as the Blues travel to West Brom and Manuel Pellegrini's side take on Sunderland at the Etihad.
