Frank Lampard has insisted Roman Abramovich does not have unrealistic expectations of his Chelsea side when it comes to winning the Champions League.
Abramovich famously fell in love with Europe's premier club competition when he watched Manchester United play Real Madrid in a thrilling tie eight years ago.
And since buying Chelsea later that same year, the Russian billionaire has become obsessed with winning the European Cup.
No team has gone closer in the interim without actually achieving that dream and Abramovich has been painted as a character who has become increasingly impatient with the failure of successive managers to deliver the ultimate prize.
But ahead of the quarter-final first leg against Manchester United - a repeat of the 2008 final - Blues midfielder Lampard claimed the club's owner knew full well the enormity of the challenge.
"I'm sure the owner would be very pleased for us to win it," Lampard said. "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."
