The Blues face United twice in the next week in a quarter-final which is a repeat of their agonising final defeat in Moscow three years ago. Wednesday's first leg will be Lampard's 500th Chelsea appearance and there is no doubt which was his most painful game for the club. But the 32-year-old says he is too old to bear a grudge over events of May 2008. "I really promise you, revenge certainly isn't in our minds," said the midfielder, who scored the equaliser in a final which Chelsea lost on penalties. "When you play for a long period of time, as I have here, you see the ups and downs. You collect them. "You don't any feel thoughts of revenge or anything against anyone. "You understand you can't always be successful and win." Lampard has certainly learnt that the hard way, having also suffered four semi-final defeats in the past seven years. Add to that several calamities with England and the midfielder has plenty of disappointments to add to the many trophies he has won. "There have been a few painful ones, with England as well," he said. "They're obviously horrible feelings." Billionaire owner Roman Abramovich has also learnt realising his long-held dream of turning Chelsea into champions of Europe is not as easy as he may have thought. Lampard said: "I think we've given him some very good times. "And I know the owner has appreciated it from how he's enjoyed them with us when we've won titles and cups. "But the Champions League's a huge thing. "I'm sure the owner would be very pleased or us to win it. "But at the same time, he doesn't come in every day and knock our door down, saying, 'Why have I not won this yet?' "He understands it's the most difficult competition in football."
