Phil Thompson believes Manchester United manager Jose Mourinho doesn't trust Marcus Rashford.

The 20-year-old has not started since the opening day win over Leicester City, with Romelu Lukakuthe preferred option.

"Marcus Rashford is a very talented boy," the Soccer Saturday pundit told Sky Sports News. "Is he going to fit in at Manchester United? I don't think so.

"I don't think there is trust from the manager to the player that he can do it on a regular basis. That is why he is only coming into the team now and again.

"He is only 20 years old and he probably needs a little more time, but I think this season is a big season for him. Come the end of the season he then has to make the decision.

"He's got to start playing regularly."
