Rashford burst onto the scene at Man United in February and has since gone on to score seven goals since his debut for the club.
The 18-year-old has featured heavily for United recently and there were fears that he could burn out but van Gaal says precautionary measures are being taken.
“I have changed him after 70 minutes [vs Aston Villa], I believe, and that is also to give him a little bit of rest,” van Gaal said.
“He didn’t train the day after and also the day after that he didn’t train. I want to keep him fresh because he is in the momentum of scoring and that is very important for him but also for the team.”
There are often fears of placing too much pressure on young players, too early, in their careers but Rashford seems to be handling the workload, mentally and physically.
He has been in scintillating form recently and that has made it very hard for van Gaal to leave him out of the side. Hopefully he scores again when United take on Crystal Palace on Wednesday.
