Rojo picked up a knock in the 3-2 win over Arsenal on Sunday, meaning he had to be replaced by Timothy Fosu-Mensah after 55 minutes played.
The Argentine has only just returned from a dislocated shoulder and there were fears that he could be set for another lengthy absence.
Speaking about Rojo’s injury, van Gaal said: “I don’t think it is serious; it was a kick. We have to wait and see, of course. It was also a good position that I gave him the first minutes to play. My plan was already 60 minutes. He didn’t reach the 60 minutes because of the kick.”
Rojo has performed well whenever he has been on the pitch for United but he always seems to get injured just as he is building up a head of steam.
Much like Phil Jones, Rojo needs to stay clear of injury and get a run of first team games under his belt. Rojo has shown that he has what it takes to succeed at United but patience may wear thin if he continues to spend time on the sidelines.
