Ajax chief executive Edwin van der Sar says they're happy selling their players to the likes of Manchester United and Real Madrid.

Unlike some of Europe's biggest clubs, Ajax are not afraid of their youngsters attracting attention.

“It sounds strange but we are almost honoured if Real Madrid, Barcelona and Manchester United are coming for our players," Van der Sar said.

"Of course, I'd rather keep them but, having been a player myself, if you give us great service, league titles and commitment, then we think with you and set you along for the next part of your career.

"But we hope that you come back to Ajax and play for another one or two years, come onto our coaching staff or be like myself and Marc."
