“Back to work @santandave 🎶✌🏾😄.”

Fellow Man Utd man Andreas Pereira reacted to the post with a simple: “Rashy 🤩.”

While Arsenal legend Ian Wright added: “💪🏾.”

Rashford has returned to the gym just two weeks after he got engaged to his childhood sweetheart Lucia Loi in Hollywood.

He popped the question at the end of May as they toured celebrity hangouts in Los Angeles.

It comes after a difficult season for Rashford at Old Trafford.

He managed just five goals and two assists in 32 appearances for the Red Devils.

And his poor run of form has seen Gareth Southgate drop him from his England squads in March and June.

Explaining the initial decision to leave him out in March, the Three Lions boss said: “He [Rashford] is in the same position as everyone else.

“In the squad or out of the squad they all have to play well over the next period of this season and the beginning of next season.

“It’s a difficult time for him. He is clearly not at his best.

“There is plenty of time and we know what he can do and hopefully he can rediscover his form.”
