Marcus Rashford Hat-Trick helps United thrash RB Leipzig.

Marcus Rashford came off the bench to bag an impressive hat-trick as Manchester United thrashed RB Leipzig.

A precise pass from Paul Pogba set Mason Greenwood on his way before the teenager produced an incisive finish into the bottom corner to get United going.

Rashford was then introduced to take the game away from the Bundesliga league leaders.

The 22-year-old got his first when he ran on to Bruno Fernandes’ through ball to place a shot past Peter Gulacsi, before adding his second minutes later with a powerful low drive.
