Nemanja Vidic believes the gut-wrenching feeling of losing a Champions League final will drive Manchester United to do better this term.
United tackle German champions Wolfsburg at Old Trafford on Wednesday looking to maintain a positive start in Group B.
Victory will leave the Red Devils tantalisingly close to booking their place in the knockout phase after just two games.
Yet it is only in Madrid next May that United can truly exorcise the ghosts of Rome and the defeat to Barcelona.
"It is a very bad feeling when you go to a final and lose and that one is a particularly bad memory," said Serbian defender Vidic.
"You do have to acknowledge it is better to get to the final and lose than not be there at all and that to stand up you need to sit.
But it is hard. We all know how we felt. We need to make sure it doesn't happen again."
