Lyon striker Lisandro Lopez has called on his team to take more risks ahead of the Champions League semi-final second leg against Bayern Munich on Tuesday.
Lyon lost the first tie in Germany 1-0 and Lisandro said: "The team must change its attitude, its mentality.
"We played too defensively and now must have a more positive mind-set. We must change tactics if we are to progress."
Lyon midfielder Jeremy Toulalan and Bayern winger Franck Ribery are suspended after first-leg sendings off.
Danijel Pranjic is banned too and Bayern are also certain to be without midfielder Anatoliy Tymoshchuk, who came off the bench in the first leg, as the Ukrainian has a stomach virus.

Coach Louis van Gaal also has concerns over central defensive pair Martin Demichelis and Daniel van Buyten as well after they picked up knocks in the 1-1 league draw against Borussia Moenchengladbach on Saturday.
Even though a draw will take Bayern into the final, the Dutch coach says he will instruct his players to take the game to their French hosts.
"We are not the kind of team whose aim is just to avoid conceding goals when we enter the field," said Van Gaal. "I've never told my players to play like that since the beginning of the season and I won't start on Tuesday.
"We have many injuries and many problems. We have brought 17 players and if they cannot play, then we will still have 14 players. We will still be able to field 11 players.
"When I was a coach in the Netherlands and we had to play against a German team, I used to tell my players that they had to be ready to play until the very end of the game.

"Our team is made up of German players and of foreign players who have been playing in Germany for quite a long time and are now immersed in this special German mentality."
Lyon have a big doubt over defender Cris, who picked up a knock in the first leg, and winger Michel Bastos, who limped out of training on Friday clutching the back of his right leg.
But former Rangers and Newcastle defender Jean-Alain Boumsong has resumed training following a calf injury and should at least be on the bench.
The French club's manager Claude Puel is confident his side can turn the tie around and reach the final in the Bernabeu on 22 May despite a lacklustre first-leg display.
"We played with the handbrake on in Munich," he said. "But we still have our chances for the return leg.
"We went to [Real] Madrid and qualified and now we will go and do it at Stade Gerland. I prefer this kind of scenario, because you play your best football when you need to get a result.
"Without being overly optimistic, I think we have every chance to qualify simply by playing to our ability."
