Manchester United fullback Patrice Evra says over-confidence cost them last season's Champions League final against Barcelona.
United are aiming to stay on course for a third straight final by overcoming AC Milan at Old Trafford on Wednesday to book a quarter-final place.
Ahead of that game, which will see David Beckham face United at Old Trafford for the first time since his 2003 exit, Evra admitted United's arrogance cost them against Barca.
"First and foremost, Barcelona won because they played really well," said Evra. "But even so, I'm frustrated because I feel that we didn't show the real face of Manchester United.
"We were a bit too confident and sure of ourselves, and we were caught cold. We start each season the same, with the desire to go all the way in every competition. At United, winning one title per season just doesn't cut it.
"We're obliged to win several, if not all of them. This year, the main goal is to win a fourth championship in a row, which would be historic.
"But we're also hoping to win the Champions League again, because the defeat in last year's final still sticks in all our throats. Personally, though I've already won it, I'd like to win it three times before ending my career.
"I've played in three finals, one with Monaco and two with United, and lost in two of them.
"So my objective is to win it again, knowing that it would also give us the chance to compete to become world club champions once more."
