Romelu Lukaku haunted West Ham United yet again as he netted twice on his Premier League debut for a rampant Manchester United in a 4-0 win on Sunday.

Lukaku netted either side of half-time before Anthony Martial and Paul Pogba completed the scoring against slow-starting West Ham, who lost their opening Premier League game of the season for the 11th time.

The Belgian striker, who cost United £90m this summer from Everton, has now scored 11 times in his last 11 league appearances against the Hammers.

The result means Jose Mourinho still has never lost a home match on a Sunday in all competitions - a run stretching 112 games.

Team news Two summer signings were handed starts for Manchester United - Nemanja Matic and Romelu Lukaku, but Victor Lindelhof didn’t make the squad. West Ham gave Premier League debuts to four new additions – Joe Hart, Pablo Zabaleta, Marko Arnautovic and Javier Hernandez.

United's main problem last season was scoring at Old Trafford as they managed just 26, which was two less than relegated Hull City. Lukaku was snapped up to improve that tally and took just 33 minutes to introduce himself to his adoring crowd.

Marcus Rashford - lively throughout - sprinted at the heart of the West Ham back four and slipped a delightful ball through to the Belgian, who smashed a first-time effort past Joe Hart via the inside of the post.

Lukaku didn't have to wait long until after the break to double his league tally. Mkhitaryan clipped a free-kick into the box from the left and Lukaku rose ahead of his marker Arthur Masuaku, who seemed to be sharing a joke with the striker before the ball was played in, to glance home from eight yards out.

West Ham almost replied instantly when Edmilson Fernandes' cross found Marko Arnautovic, who got the wrong side of Daley Blind, but his header was tipped onto the crossbar by David de Gea. That was as good as it got for the visitors as they struggled to get former United man Javier Hernandez into the game on his full debut.

United pressed on for more goals as Lukaku hunted a hat-trick. He was denied by a brilliant sliding block from Pablo Zabaleta on 64 minutes before Rashford struck the inside of the post with a fabulous effort from 25 yards.

With West Ham pushing for a late salvo, United struck twice late on with Martial finishing off a flowing move instigated by Henrikh Mkhitaryan and Pogba curling home a fantastic effort from 20 yards.

This was Mourinho's biggest Premier League win as United manager, and their biggest home win in the Premier League since his Chelsea side beat Arsenal 6-0 in March 2014.

Man of the match: Nemanja Matic

Man of the match - Nemanja Matic

"I can't think of one reason why Chelsea sold him." That was Gary Neville's assessment after Matic's impressive display on his Premier League debut for Manchester United.

The midfielder won possession more times than any of his team-mates (11), played more passes (69), had more touches (89) and covered more ground (11.41km). As if that wasn't enough, he also got the crowd out of their seats when he embarked on a mazy run down the right wing that saw him jink past several West Ham players.

The pundit - Gary Neville

"I have never seen this league won without power and pace and a really strong spine and it looks like United have got that. They look like they are going to mount a challenge. It's day one, but they look like they have the attributes to mount a challenge for the title because they seem like they have everything.

"There is no excuse for Man Utd not to challenge for the league. That's not putting pressure on the players or Jose Mourinho, but they have to challenge with the money that has been spent and the players that have been brought in.

"Last season was not good enough in terms of the Premier League, nowhere near good enough. It was a massive under-performance from those players so they have to get back up there this year."

The managers

Jose Mourinho: "We didn't start especially well, maybe we were a bit nervous, but then we had a quality performance, with good personality and word which I like - "confidence".

Manchester United boss Jose Mourinho said his side produced a quality performance full of confidence

"The team played with lots of confidence and even at 2-0 they were confident and kept playing football. I was happy and it was a very positive performance.

Slaven Bilic: "I expected more. I have to admit they were much better in every aspect, they were better in the air, on the floor, in 50-50 challenges, we knew they had a strong side but I expected us to do better. We started ok, then it was missing, we were much slower than them."
