Manchester - Marcus Rashford scored twice as Manchester United made the perfect start to their Premier League season by inflicting a 4-0 defeat on Frank Lampard in his first match in charge of Chelsea on Sunday.
Ole Gunnar Solskjaer's men were in need of a fast start to the campaign to erase memories of a terrible end to last season and got it, as Rashford's early penalty and three goals in 16 second-half minutes from Anthony Martial, Rashford and debutant Daniel James had Old Trafford in raptures.
Harry Maguire and Aaron Wan-Bissaka also impressed at the back on their debuts after United spent Pound 130 million on the pair over the summer to shore up a defence that conceded 54 Premier League goals last season.
"It is a great start for myself and the team. We rode our luck a bit first-half but second we were much more ourselves," said Maguire, who won man-of-the-match in his first game as the world's most expensive defender.
"We knew there were only two clean sheets last year here (at Old Trafford). We need to make it a fortress."
However, questions will be asked of Chelsea's decision to let experienced defender David Luiz leave to join Arsenal earlier this week as the Blues struggled to contain the United counter-attacks despite dominating long spells.
Lampard's first team selection was a bold one as he put his faith in youth with Tammy Abraham and Mason Mount handed starts, while Pound 60 million signing Christian Pulisic was made to wait for his Premier League debut on the bench.
"The team we put out today was clearly competing in the game for long periods but we made four mistakes and they were clinical in the way they put them away," said Lampard.
"It was nowhere near a 4-0. Four mistakes for the goals, but we controlled major parts of the first-half. We hit the woodwork, (made) poor decisions in the final third, we should be in the lead at half-time.
"They are a counter-attacking team, it's a big strength, they have pace, and if you give them opportunities they will counter. For massive parts of the game we didn't allow them to do that. (There are) loads of lessons for us."
Chelsea started the better as Abraham smashed a shot from the edge of the box off the post, but the heart of Lampard's defence always looked fragile.
Kurt Zouma had already gotten away with gifting possession to Martial on the edge of his own box as the Frenchman shot weakly into the arms of Kepa Arrizabalaga before he was turned easily by Rashford and hauled the England striker to the ground.
Rashford dusted himself off to blast the penalty high past Kepa to open the scoring.
United needed David de Gea to recover his best form as he made fine saves from Ross Barkley and Emerson Palmieri, while the Italian international also blasted off the inside of the post.
But at the other end, Rashford and Martial provided the clinical touch to kill the game off in the space of 60 seconds that Chelsea lacked.
Maguire showed his presence to outmuscle Abraham on the edge of the United box and set off a flowing counter-attack that ended with Martial bundling the ball home at the far post from Andreas Pereira's cross.
Paul Pogba then played provider with a brilliant ball over the top for Rashford to burst in behind before coolly slotting past Kepa.
Pogba was the creator again for the fourth as the Frenchman played a one-two with Rashford and powered through the Chelsea defence before laying off to James, who got the benefit of a big deflection to find the bottom corner.
