"I'd rather win tomorrow than on Monday against Juventus," he said.
"Losing is not a problem in and of itself. But if I win tomorrow, then I'll win on Monday too. But I don't like talking about 'if'.
"Of course this match could turn our season around. Winning would take us into the Last 16. We'd pick up confidence and we'd face Juve with a different heart.
"Tomorrow's game could have after-effects on the whole year."
