Owen Hargreaves admits Manchester United have a burning desire to win the Champions League.
And how does Hargreaves know? Well, he has been studying it all through the pages of Roy Keane's autobiography.
"But I'm reading Roy Keane's book and he says the most important thing at the club is the Champions League.
"There is a conversation with him and Alex Ferguson, who says that without him they can win the Premier League but they need him fit to win the Champions League.
"He pulls Jaap Stam up when Stam says the priority is the league title and tells him it's Europe.
"The book came out a while ago and I can't say whether the manager would say that these days but, there is a totally different atmosphere at Old Trafford for European games than for domestic fixtures.
"United now considers itself a global brand and it needs success in Europe to strengthen that position."
The former Bayern Munich star also told The Sun: "I was in the stadium that night in '99. Bayern played really well and should have won the game.
"We just threw it away in the last five minutes. We were shocked more than anything, standing in our Bayern tracksuits having cheered the team on.
"I lost my voice because we screamed so much. We just sat there shocked because it had looked so comfortable.
"And then, suddenly, the cup was gone. It made us more anxious rather than more determined when we found ourselves in the final in 2001.
"We didn't want to have to go through that again."
