says have a ‘potential world star’ in – but suggested his former club overpaid for the Brazil international.
Erik ten Hag made his former winger a top transfer target in his first summer in charge with United seeing a number of bids rejected by .
Having already raided the Dutch giants for Lisandro Martinez, Ajax stood firm on their huge valuation of the 22-year-old with United eventually getting the deal across the line for £85million, making him their most expensive signing of all time after Paul Pogba.
Antony has already made an impressive impact at Old Trafford, scoring in his first three games for the club against Arsenal, Manchester City and Everton.
Former United goalkeeper van der Sar, who worked alongside ten Hag at Ajax as CEO, admits the club were eager to keep the winger for another year but could not turn down the huge offer from Old Trafford.
‘Still young, still potential,’ van der Sar told .
‘We would have liked to keep him here one year longer — there was not a dire need to sell him, we had money in the bank — but the fee got so high.
‘We challenged United to go as far as possible. They have a potential world star.’
United also paid top dollar to sign Martinez from Ajax, putting up £56million for the Argentine who has been an instant hit in the Premier League.
Arsenal were also interested in signing the centre-half but van der Sar revealed negotiations with the Gunners never got started.
‘Arsenal came earlier for Lisandro, but it was an amount where we said, ‘Thank you very much for the offer, but we’d rather keep the player than start negotiating’.
‘With United, it was a little bit different. Over the years we have had a few conversations: Daley Blind, Donny van de Beek.
‘My job is making sure I make the best decisions for Ajax.’
