Manchester United defender Harry Maguire has issued a rallying call to his teammates as Ole Gunnar Solskjaer's side look to secure Champions League football for next season.
Following their 2-0 victory over arch-rivals Manchester City at Old Trafford on Sunday, United are only three points behind fourth-placed Chelsea in the Premier League table.
Sunday's victory stretched United's unbeaten run to 10 games, and Maguire is calling upon his teammates to avoid complacency as the race for European football hots up.
"We need to build on clean sheets. It is a foundation," Maguire told MUTV.
"Eight in 10. Defensively, all season, we have not been a team that has been all over the place and conceding numerous chances. We have never been that team.
"We have conceded sloppy goals at sloppy moments. Set-plays, long-range shots, special goals but, lately, we have cut it out.
"I didn't feel there was any need for me to start telling the full-backs or centre-halves to start jumping more, or trying to start putting pressure on higher up the pitch because we were 1-0 up and didn't feel under threat in terms of them creating chances.
"It is nice to do the double over them but, most importantly, it is a big three points to close the gap on where we want to be at the end of the season."
Solskjaer's side also remain in the hunt for the FA Cup and the Europa League.
