Olympique Lyonnais president Jean-Michel Aulas revealed the club will not exercise the option to bring in a replacement for injured midfielder Nabil Fekir.
Fekir sustained a severe injury during France's 1-0 friendly win over Portugal on Friday, rupturing a cruciate ligament in his right knee and is expected to be out until at least February next year.
Ligue 1 rules dictate that clubs are allowed to sign a replacement player outside of the normal transfer window in the event of such an injury on international duty, but Lyon remain adamant their squad can absorb the loss.
"The rule isn't in our favour, because any potential reinforcement could not be included in the Champions League squad," Aulas explained. "He could only play in the league.
"We all agreed to say that we have great confidence in the squad.
"We said to ourselves that to sign a new player when Nabil is going to have an operation would not be the best thing, and it will also allow the youngsters to establish themselves.
"It's our strategy to give the youngsters a chance. And Alex [Lacazette] is going to be in a position to help us.
"I have great confidence in him. It's an opportunity for us to get our great Alex back."
