Marcus Rashford scored twice as Manchester United condemned former manager Jose Mourinho to defeat on his return to Old Trafford and ended Tottenham's three-match winning steak under the Portuguese.Rashford beat Tottenham keeper Paulo Gazzaniga at his near post after six minutes after the ball had broken to the England forward off Davinson Sanchez.Then, after a long wait for a VAR check, Rashford kept his nerve to convert a penalty four minutes after the break, once it had been ruled the striker had been fouled by Moussa Sissoko.Dele Alli had equalised with a brilliant goal at the end of the first half but United were good value for their victory after creating a number of excellent chances they failed to take.Rashford was unable to become the first United player to score a league hat-trick since Robin van Persie's memorable effort against Aston Villa in 2013 but he now has 12 goals in 13 games for club and country, and his nine Premier League goals leave him one short of his season best.
