Rashford and the rest of the United substitutes had been going through their stretches close to the touchline.

However, the forward was then seen storming away from the group as Christian Eriksen and Antony tried to stop him.

Footage shared to social media showed Rashford had earlier been involved in a heated back-and-forth with a supporter.

He could be seen looking over to the stand before heading to the edge of the pitch.

The 26-year-old walked away from the rest of his team-mates to confront the member of the crowd.

Fans could be heard in the background of the video shouting “Rashford, don’t listen to him.”

Rashford made his return to the squad for the visit of Newcastle after being named on the bench by Erik ten Hag.

He has not appeared since picking up a knock in the FA Cup semi-final against Coventry on April 21.

The academy graduate has scored eight goals and provided five assists in 40 appearances for the Red Devils this season.

However, he has scored just twice in his last 10 Premier League matches.

Rashford has even been linked with a move away from the club this summer, but is prepared to resist any attempts to sell him.

It comes with United willing to listen to offers of over £80million for Rashford, with four years remaining on the contract he signed last summer.

Rashford would come on for a seven-minute cameo at the end of a 3-2 win for Man Utd.
