Manchester United started the new Premier League season with a 4-0 victory against Chelsea at Old Trafford.
United new-boy Harry Maguire revealed he told his team-mates to keep their concentration and keep a clean sheet even after going four goals ahead of Chelsea.
"I was reiterating on the pitch that we need to concentrate now, even after 3 and 4," Maguire told Sky Sports.
"We wanted a clean sheet. We knew coming into the season that there was only two clean sheets here last year.
"We've really got to make this a fortress and make this our place to come and score. It's a good start. We're not getting carried away but we'll keep working and keep improving."
Maguire was named man of the match after a rock-solid display after becoming the world's most expensive defender.
