The English striker has struggled for form under Jose Mourinho. Metro further states that Lukaku has blocked Rashford from playing in his preferred central position. But the Belgian has been taking one-on-one sessions with the latter after finishing each training session.

The Englishman is a real talent but he needs to be patient and grab the opportunities handed to him in cup games. He could be a vital player for us in the future.
We have seen some glimpses of his ability as he scored two goals for England in the international break. For now, however, learning with Lukaku could be an important thing.
Rashford needs more game time in order to acclimatize himself in the playing system. Mourinho must deal with this situation carefully and try to extract the best out of the youngster along with Lukaku.
