Manchester United legend Edwin van der Sar is keen for Louis van Gaal to tap into the club's academy.

Callum Gribbin scored both goals in an Under-13 match between United and Ajax ahead of van der Sar's testimonial at the Amsterdam Arena in 2011. Edwin's son Joe was also involved in that game, so he is well aware of the emerging talents back in Manchester.

"I know Gribbo also from the time when I watched the sessions with Joe at the Aon Training Complex and it's great," Ajax marketing exec van der Sar told manutd.com.

"There are some others, I think Marcus Rashford is another of the kids there and, last year, you took a player from our youth academy - Timothy Fosu-Mensah. I saw his name also on the Under-21s' bench recently so I'm getting the updates from the Under-18s and it's good.

"It's important for us, it's our philosophy, to focus on youth and the transition from the Academy into the first team and I think Louis has that also. He will always have a look to see which young players there are to bring through."
