There have been some sensational results already in the UEFA Champions League last 16 and Olympique Lyonnais are hoping for another when they take on FC Barcelona on Wednesday at the Camp Nou.
UEFA Champions League last 16, second leg
FC Barcelona - Olympique Lyonnais
OL know the size of the task that awaits them in Catalonia even after they battled gamely to a 0-0 draw at home in the first leg last month. Barcelona are unbeaten in their last 29 home games in the competition, winning 26 of those. However, Lyon can take inspiration from the way Ajax and Manchester United went away from home last week and, against all odds, knocked out Real Madrid and Paris Saint-Germain respectively.
"That does give us a few ideas. There have been a few surprises, but even without that we have come here to create a sensation," said skipper Nabil Fekir at Tuesday's eve-of-game press conference.
"It will be very complicated. We must not make any mistakes because in Champions League games little details make the difference. Barça are favourites but we have come here to win."
It is nine years since Lyon beat foreign opposition in a Champions League knockout tie. That time it was Madrid, and 5,000 away fans will be up high in the Camp Nou on Wednesday hoping for a repeat performance.
"We are competitors. We have great players, with a certain maturity even if the team is young," added Fekir. "It is a dream to play here at the Camp Nou in the Champions League, but that is not the most important thing. We have come here to qualify. We don't have much to lose - Barcelona are favourites and we will play with no fear."
Fekir's return is a big boost for the visitors after he sat out the first leg through suspension. He will come back into the starting line-up having been on the bench at kick-off for last weekend's 2-2 draw at RC Strasbourg Alsace.
Marcelo set to miss out
Marcelo came off early on in that game with a hamstring problem and the fitness of the Brazilian defender has been a major source of concern for coach Bruno Genesio. He named Marcelo in his travelling party for the game, but a late decision will be made on whether he plays, with Kenny Tete or Fernando Marçal standing by to replace him.
"We know what awaits us here. We know it will be difficult, that we will be up against one of the best teams in the world, but we also know that we have already done it," said Genesio. "We will need to be humble, but also have lots of confidence in ourselves. We will have to give everything, and show the people who believe in us that we belong here."
Barcelona have a fitness worry of their own in the shape of France star Ousmane Dembélé, as they look to ensure there will be a presence from La Liga in Friday's draw for the quarter-finals - Atlético Madrid's elimination on Tuesday means they are already the sole survivors.
"Tomorrow's game is 90 minutes in which anything can happen. You can have a moment of glory...and some bad luck that can determine the outcome of the game. We are determined to play well," said coach Ernesto Valverde.
