West Ham United 3 Manchester United 1

Felipe Anderson's fifth-minute flicked finish and a wickedly deflected shot by Andriy Yarmolenko, later chalked up as a Victor Lindelof own goal, put the Hammers 2-0 up for half-time.

Although substitute Marcus Rashford pulled a goal back with a sublime backheel to outshine Anderson's fancy effort, Marko Arnautovic almost immediately restored the two-goal gap to make the painful final score 3-1.

After being pegged back to a draw against Wolves the previous weekend, Jose Mourinho made four changes to his starting XI, which included handing a first start of the season to Scott McTominay.

The 21-year-old was joined by Ashley Young, who skippered the side, Nemanja Matic and Anthony Martial, who all featured in Tuesday’s midweek cup exit to Derby County.

It was West Ham that started the brighter of the two teams. Fabian Balbuena had an early effort on goal, but the Paraguayan’s header did little to trouble David De Gea as it was skewed wide of the target.

However, the Hammers edged in front minutes later. Pablo Zabaleta was able to run in behind the Reds' defence and the former Manchester City player’s low cross was coolly flicked past De Gea by Anderson to put Manuel Pellegrini’s side into the lead.

It was a difficult opening for Mourinho’s men. Marko Arnautovic very nearly doubled the hosts’ lead ten minutes later, but De Gea was quick off his line to beat the athletic Austrian to the ball.

United, though, soon started to grow into the game and had a big chance to level the scores midway through the first half. A beautifully weighted cross found the head of Romelu Lukaku, however the Belgian’s effort hit the post.

The hosts, though, ended the half brightly and doubled their advantage two minutes from half-time. Andriy Yarmolenko cut inside and the Ukrainian’s crack at goal clipped Victor Lindelof to deflect past the helpless De Gea and leave the Reds with a mountain to climb going into the break.

West Ham nearly added a third goal shortly after the interval. Ashley Young’s corner was intercepted, and the Hammers charged forward on the counter-attack. Arnautovic had a go with his first touch, but his effort was fired over the crossbar.

Having made no changes at half-time, Mourinho brought on Marcus Rashford for Victor Lindelof shortly before the hour mark as the Reds continued to search for a route back into the game. Jose's side very nearly found that route when Marouane Fellaini’s downward header from Young’s curling cross forced a brilliant save from Hammers keeper Lukasz Fabianski.

As the visitors continued to apply the pressure, West Ham still posed a threat on the break. The Reds were given a warning as a through ball by Anderson was just inches away from being slid into the goal by Arnautovic.

Twenty minutes from time, Mourinho made two more changes as Mata and Fred were brought on for Martial and Pogba. Within seconds of the substitutions, the Reds did indeed have a lifeline. Luke Shaw’s corner from the left found Marcus Rashford, who leapt into the air and produced a brilliant backheeled effort which went past Fabianski, seemingly to set up an exciting final twenty minutes.

However, any hope of a late comeback was extinguished two minutes later. Mark Noble’s slide-rule pass found Arnautovic who went one-on-one with De Gea and confidently slotted the ball home and put the hosts out of sight.
