PSV Eindhoven and Man United reached an agreement over the transfer of the player on Thursday, bringing to an end months of speculation over where his future may lie.
Widely considered to be one of the best young talents in Europe, fans have been getting excited about the transfer and rightly so.
Depay helped PSV win the Eredivisie title this season and van der Sar heaped praise on the winger for his contribution.
Speaking about the transfer, van der Sar said: “Depay is not afraid. I think he’s also a little bit eager – you don’t win the title only with choir boys! In that case I think Manchester United has a future star on their hands.
“He has played tremendously well for PSV and was in the World Cup squad. He had three games – he came on and did well and scored two goals. So he had a lot of confidence coming into the new season.
“Of course he is not the finished product yet – there is still a lot to work on for him – but potentially he is a really good player and I think United have made a good deal. He’s a tremendous player and in the years to come I think he’ll show that. Louis is a great manager to help fulfil the potential he has.”
Supporters would be wise not to expect too much from Depay early on in his Old Trafford career but it is hard not go get excited about his arrival.
The hope is that his move signals the start of a busy summer transfer window for United. Ilkay Gundogan, Mats Hummels and Nathaniel Clyne have all been linked with the club as Louis van Gaal prepares his side for Champions League football next season.
