Ralf Rangnick backed 'abundant talent' Marcus Rashford to rediscover his top form as wasteful Manchester United prepare to face rivals Manchester City.
The Etihad Stadium hosts the 187th Manchester derby on Sunday, when the Red Devils will look to boost their top-four chances against the Premier League leaders.
United come into the match bruised by last weekend's 0-0 home draw with Watford, where their recent profligacy in front of goal continued on an afternoon when they had 22 shots without scoring.
Star turn Cristiano Ronaldo has only scored once in 10 games but Rangnick believes things will soon turn for the team, with Edinson Cavani set to return and Rashford backed to shine in the coming weeks.
