Marouane Fellaini scored twice, while Juan Mata and Romelu Lukaku also netted as Manchester United recorded a 4-0 victory over struggling Crystal Palace on Saturday.
Palace remain rock bottom of the table on zero points, and the Eagles are now without a single goal in their opening seven Premier League matches of the 2017-18 campaign.
It took the home side just three minutes to make the breakthrough at Old Trafford, with Mata finding the bottom corner with a super finish after Rashford had driven down the left before picking out the Spaniard.
Palace had a decent chance to level the scores in the eighth minute when Mamadou Sakho met a free kick from Yohan Cabaye, but the former Liverpool centre-back saw his header miss David de Gea’s crossbar.
Mourinho’s side doubled their lead in the 35th minute, however, when fit-again Fellaini converted a brilliant Ashley Young cross at the far post as Palace were hit with a killer blow 10 minutes before the break.
Man United had a half-chance to score their third early in the second period when Rashford delivered a dangerous cross towards Lukaku, but Damien Delaney just about did enough to clear behind.
Palace continued to press forward in the latter stages, but it was Man United that had the better chances – Martial bringing a smart save from Hennessey, before Lukaku finally got his name on the scoresheet in the 86th minute after converting a low cross from Martial at the far post.
Next up for Man United is the small matter of a trip to Liverpool after the international break, while Palace’s search for their first league point of the season will continue away to the champions Chelsea next time out.
