United made history in the last-16 by overturning a 2-0 home defeat against Paris St Germain to win the tie on away goals with a dramatic 3-1 victory in the French capital.
Barcelona defender Gerard Pique has urged his side to make sure they do not leave Manchester United room for another heroic comeback in the Champions League when they visit Old Trafford in Wednesday`s eagerly-awaited quarter-final first leg.
United made history in the last-16 by overturning a 2-0 home defeat against Paris St Germain to win the tie on away goals with a dramatic 3-1 victory in the French capital, underlining the club`s reputation for stirring European revivals.
“The PSG game should serve as an example for us that you cannot afford to leave Manchester United alive, if you can beat them with lots of goals then you have to do it,” Pique told a news conference on Tuesday.
“That game should remind us that we have to be very concentrated, as United are a very dangerous team.”
Pique, 32, spent his first years as a professional with United, joining the club aged 17 but returning to Barca in 2008 after failing to hold down a place in the team due to fierce competition from Rio Ferdinand and Nemanja Vidic.
But he said his experience at United was invaluable to his development.
“I went from being kid to an adult here, I had my first experiences as a professional and some crazy experiences off the pitch. I came here alone, without my family, I learned a lot and I left a completely different person,” he recalled.
“I remember Ole as a great teammate, I was 17 and he was a veteran and for sure he helped me adapt to the club, to the country and to the city,” Pique added.
“It was a great experience to train alongside him, he helped me a lot so I`m happy to see him in charge of Manchester United. He`s done a great job, won lots of games and got them playing much better. Tomorrow will be tough and I hope we can win.”
