Van de Beek is expected to join United from Dutch giants Ajax in the coming days and he would become Ole Gunnar Solskjaer’s first signing of the summer.
Ferdinand appears to be delighted with the move as he tweeted his excitement ahead of the 23-year-old’s impending transfer.
Van der Sar swiftly responded to his former team-mate, though the Dutch legend appears to not want to lose his star.
Van der Sar posted a crying emoji in response to Ferdinand, suggesting the deal is very close.
Reports suggest that Van de Beek is likely to take the No 34 shirt should he join up with the Premier League giants.
His Dutch team-mate, and Liverpool star, Virgil van Dijk believes a move to Old Trafford is a good one for the midfielder.
"[The Van de Beek transfer] looks like it's going to happen indeed," said the Premier League winning defender.
"From my heart, I wish him the best. It's wonderful for him, it's a nice step for him to move to a great club as a Dutch player.
"Also the same for Nathan Ake, who moves to Manchester City. I'm glad for both of them.”
While Rafael van der Vaart added: “Donny deserves this transfer so much. He has played excellently for Ajax.
