With only nine days until their game against Spain, Van Persie is still in the middle of a race to fitness but has made great strides towards re-gaining his full match sharpness.
The 30-year-old hasn’t been completely fit ever since spraining his knee against Olympiacos but Van Gaal has praised the decision of David Moyes and his staff of letting Van Persie undergo treatment in Holland.
“He is coming out of injury, you know that. We built him already up in our federation, our medical department,” he said.
“It was under the permission of David Moyes. So we could control him. He has worked very hard. Then he played two matches of 20 or 30 minutes and the last match 30 minutes.
“We did not expect that as the injury was bad. It was not so light. De Guzman [who suffered a hamstring injury in training on Monday] was much lighter I think.
“Van Persie had a heavy injury. So I think of course he is not 100% fit. He is not 100% fit. But he can play.”
When asked whether Van Persie was guaranteed to be ready for the game against Spain on June 13, Van Gaal replied: “No. we have two weeks to go. But I think he will be 100%.”
A fully firing Van Persie for Holland and Van Gaal would be great for United fans and Van Persie himself ahead of the new season, so hopefully he can return to his best form out in Brazil.
