Bruno Genesio cited Lyon's win over Manchester City as inspiration in their second-leg match against Barcelona.
“We will need a perfect match to qualify, but we can do it. Look at the game we played at Manchester City where we deservedly won – this will be a different game but the difficulty level is the same, and that will inspire us," said Genesio.
The manager added that his side will not man-mark Messi.
“Lionel Messi is incredible, but we do not plan to man-mark him individually and will look at other ways to limit the potential damage he can inflict upon us. Barcelona have so many quality players that we must not focus on just one.”
