Moussa Dembele has warned his Lyon team-mates to expect a lot of noise at Ibrox but reports in France claim the former Celtic striker will miss the game against Rangers.
Dembele has scored four goals in three games ahead of Thursday's Europa League group opener but reports in French media say the 25-year-old will miss out on a trip to Glasgow because of a muscle injury.
An interview with Dembele appeared on Lyon's official website on Tuesday evening with no mention of his fitness issues.
Moussa Dembele has warned his team-mates about the Ibrox atmosphere Dembele, who scored seven goals against Rangers in two seasons in Scotland, said: "I've had some great battles against this team. I know what to expect. It's a team that plays well on the ball and gives their all. I scored my first hat-trick against them.
"I have played in the Champions League in Scotland. I have seen some pretty crazy atmospheres. There is going to be a lot of noise on Thursday."
Dembele has set his sights high in the tournament. "It's a great competition with very great teams," he said. "It's our Champions League.
Rangers boss Steven Gerrard : "They are arguably the best [European team I've faced as Rangers boss]. At full strength, Lyon are very much a Champions League team with Champions League- calibre players, they have a manager who got this job on the back of doing ever so well as the Bayer Leverkusen manager.
"He has been here before, he knows what we are about so this is a real big test tomorrow and there is no doubt about it we have to be at our best and that goes for both sides of the game.
"We have to have a high level of focus and concentration tomorrow because if you don't against these teams you can be punished and punished very quickly so it is a real good test and challenge.
"But we have to have our own confidence and belief that we can play at this level, we can compete and at the right times during the game, we have to show bravery that we can hurt the opposition as well.
"We are excited, we are looking forward to it but we know the size of the challenge and it is arguably the biggest we have had as a group."
Filip Helander has had surgery on a knee problem which will keep him out for "the foreseeable future", according to Rangers manager Steven Gerrard.
The defender was carried off on a stretcher after pulling up in the second half of Saturday's Premiership match against St Johnstone at McDiarmid Park.
Rangers manager Steven Gerrard says he is confident he has enough cover in his squad to fill in for Filip Helander who has just had knee surgery Gerrard has the remainder of his squad available to him, including Connor Goldson after the defender missed the St Johnstone match due to Covid-19 isolation.
Lyon received a boost when the Scottish Government granted an exemption for three of their international players to enter the country despite recently visiting red-list countries.
Brazil pair Bruno Guimaraes and Lucas Paqueta and Zimbabwe's Tino Kadewere have all been granted a reprieve.
However, French newspaper L'Equipe has reported former Liverpool winger Xherdan Shaqiri will miss the journey because he is not yet fully vaccinated.
