Wayne Rooney believes last season's crushing FA Cup defeat to Portsmouth provided the spur for Manchester United's players to go on and clinch a trophy double.
United were already well on their way to winning both the Barclays Premier League and Champions League when they faced Pompey at Old Trafford in March.
But, with the way seemingly cleared for them following the exit from the competition of their supposed biggest rivals, the Red Devils fluffed their lines and crashed 1-0 in the quarter-finals to the eventual winners.
'After that game, the dressing room was a horrible place to be. No words were said and club-wise it's the worst I've ever been in,' Rooney told The Sun.
'We realised that, with the other teams who were left in the competition, we would have had a great chance to win the FA Cup. It was really disappointing.
'The important thing was to keep that feeling at the back of your mind and make sure we went on to win the Premier League and Champions League.'
Despite the glorious end to their season - which reached a climax in Moscow with a penalty shoot-out victory over Chelsea in the Champions League final - the England striker insists United can get better still.
Rooney added: 'Winning the double was a great achievement - but we're not satisfied with that.
'It's something we all spoke about when we came back in pre-season - we want more trophies. We don't want to be known as a team which won the double and that was it. We want to make history.
'In five or six years I hope people are saying what a great team we became.'
