Marcus Rashford is clearly determined to impress Jose Mourinho as he prepares to report back to Manchester United for pre-season training.

The 18-year-old striker will be hoping to build on his impressive campaign last term as he broke into the Red Devils first team under Louis van Gaal.

Rashford’s impressive performances earned him a call-up to Roy Hodgson’s England squad for Euro 2016.

The forward has been enjoying some well-earned downtime in Dubai in recent days as he recharges his batteries ahead of next season.

However, the striker has been making sure that he stays as fully fit as possible but hitting the gym while away.

Rashford posted the picture above on his personal Instagram account on Monday evening and wrote: “Last bit of training getting ready for preseason before I head back to Manchester.”

Rashford will be hoping to impress new manager Jose Mourinho as the Portuguese coach prepares for his first season in charge at Old Trafford.
