Manchester United midfielder Michael Carrick has called for focus in the business end of the season.
The Red Devils are in pole position to reclaim the Premiership trophy while they booked their place in the quarter-finals of the UEFA Champions League on Wednesday.
The ex-Spurs man knows United are in a period when silverware is won and lost and wants his colleagues to finish off the great work they have started.
"The way things have gone have been tremendous, but this is where things are won and lost," he said after eliminating Lille.
"You can win everything, you can throw everything away.
"We've got to stay focused and keep doing the things we have been doing, because it's been working for us.
"Hopefully we'll finish things off and win things."
Meanwhile, Edwin van der Sar believes United could easily have slipped up against Lille after failing to kill the game off early on at Old Trafford.
The Dutch shot-stopper believes the tie was on a knife edge at 0-0 until Henrik Larsson's header on his farewell appearance settled the affair.
"I think we had two chances in the first half within the opening 20 minutes," he said.
"If we'd scored a goal I think the whole game would have been different.
"At 0-0 it was still a tricky score for us, luckily we scored the winner 15 minutes before time.
"It killed the game I think."
