Edwin van der Sar has confirmed that the Ajax board knew about Marc Overmars behaviour before they extended his contract and handed him a €1.5million (£1.25m) bonus.
Overmars, 54, left his role as director of football affairs on February 7 after sending a series of 'inappropriate messages' to female colleagues.
Now Van der Sar has revealed the Dutch club were investigating allegations against Overmars when they renewed his contract in January.
'We received signals just before that. Our supervisory board was also informed', he told Dutch publication De Telegraff.
