Ralf Rangnick has told Marcus Rashford that he will put 'all his energy' into helping the Manchester United star get out of his slump.
The 23-year-old has provided just two goals in his last 20 games and comes into his favourite fixture, the Manchester Derby, having been dropped to the bench for last Saturday's dismal 1-1 draw with Watford.
But Rangnick has sent the striker, who missed the first two months the season to recover from shoulder surgery, a promise ahead of their crucial trip to the Etihad Stadium on Sunday to face bitter rivals Manchester City.
