First team coach Meulensteen worked with many of the U21 players when they were juniors.
Blackett told manutd.com: "Rene coached us at Under-12 level, I think - we did lots of skills sessions. It shows in a lot of our players, with the good feet they've got. You don't even think about it but the skill Rene taught us comes to mind in games and you can see that in our play. I'm sure Rene is proud of us."
