Romelu Lukaku marked his Premier League debut for Manchester United with two goals to help fire his new team to a 4-0 win over West Ham on Sunday.
The £75million summer signing from Everton found the net either side of half time - first with his left foot and then via a header, before Anthony Martial and Paul Pogba completed the rout.

Romelu Lukaku was in fine form at Old Trafford, scoring twice for new side Manchester United
Manchester United (4-2-3-1)
DAVID DE GEA 6.5 – The Spaniard was alert to deny Ayew on the stroke of half-time after having almost nothing to do up to that point. Remained a virtual spectator in the second half as United bossed the game.
ANTONIO VALENCIA 6.5 – The United skipper played right-back as Mourinho reverted to a back-four and hardly put a foot wrong, other than a late challenge on Arnautovic that earned him a booking.
PHIL JONES 7 – Preferred to Smalling and Lindelof which shows what Mourinho thinks of Jones if he can just stay fit. Highlight of an assured display was a crunching tackle to stop Arnautovic in his tracks in the first half.
ERIC BAILLY 7 – The combative Ivorian was brought straight back after missing the UEFA Super Cup through suspension and showed why. Dominant in defence and a threat at set-pieces. Booked for a foul on Hernandez.
DALEY BLIND 6 – Solid on the left and provided a steady supply of set-pieces. Went close to a goal towards the end but his volley into the ground bounced just over the bar.
NEMANJA MATIC 8 – He has brought a whole new dimension to United since his £40m move from Chelsea. Anchors the team superbly and gets forward effectively – including one run past four West Ham players in the first half here. Outstanding.
Midfielder Nemanja Matic, another summer signing, also enjoyed a good Red Devils debut
PAUL POGBA 8 – United hope that Matic’s arrival will release Pogba and there are certainly signs of that working. The powerful Frenchman bullied West Ham at time and his excellent build-up play deserved more from his teammates. Capped a commanding performance with a well-taken goal late on.
MARCUS RASHFORD 7.5 – Slipped an exquisite pass into Lukaku’s path for the first goal as their partnership continues to blossom. Should have scored himself as well but steered a shot wide when clean through in the second half before hitting the foot of the post with an excellent effort.
JUAN MATA 6 – Got behind the West Ham defence twice early but couldn’t provide the finish. Faded a little after that and was the first United player to be replaced 15 minutes from time.
HENRIKH MKHITARYAN 7 – Another enterprising performance from the Armenian who provided the cross, a freekick clipped nicely to the edge of the six-yard box, for Lukaku to head the second goal and the pass for Martial to score the third.
ROMELU LUKAKU 8.5 – Hard to fault a two-goal Premier League debut. Lukaku was signed for £75m to kill off the likes of West Ham and he delivered on
