Manchester United travel to the Allianz Arena tomorrow night to face Bayern Munich and their talisman Franck Ribery.
United don't have the greatest record against Munich, having won just one of the seven Champions League meetings - THAT 1999 final.
And to progress, they must get the better of the two-time France footballer of the year Ribery.
He is not in the prime of health after tendinitis worries this season.
Butt the France winger will be the man for United to watch, especially if Arjen Robben fails to regain his fitness in time for the clash.
Sportsmail takes a look at why the boy from Boulogne is the Germans' danger man and just why they slapped a 100m Euros price tag on him last year.
Goal of the season v Nantes, 2005Ribery enjoyed two seasons at Marseille after his controversial move from Turkish side Galatasaray.
He settled in very quickly and scored this gem against Nantes, which was later voted goal of the season by the club's fans.
World Cup goals v Lithuania, 2009Despite his poor luck with injuries, Ribery has still managed 42 appearances for France, and netted seven times. And he has scored some vital goals, too.
France barely scraped through to this summer's World Cup and have his two winners in qualifiers against Lithuania to thank for making it to South Africa.
Late winner v 1860 Munich, 2008There are late winners and then there are last-minute of extra-time winners. Oh, and when they are scored against your city rivals, well, that's the stuff dreams are made of.
Ribery slotted home a (very) late penalty against 1860 in the German Cup with the last kick of the game to cement his hero status at Bayern.
Penalty v England, 2008Not prolific for his country but an nine month spell without a goal for France came to an end with this goal against England.
It was Fabio Capello's first game in charge England on foreign soil and Ribery sealed the occasion with his 32nd-minute penalty.
So exuberant were his celebrations that he was booked straight afterwards for removing his shirt.
Long-range rocket v Stuttgart, 2008And if you were still unsure as to whether Ribery will be a danger against United, take a look at this goal.
This stunner against Stuttgart means that Edwin Van der Sar will always have to be on his toes - even if Ribery is in possession 35 yards from goal. Scorcher.
