Lyon midfielder Clement Grenier feels that his penalty miss against Reims on Saturday was crucial in the game's outcome.

Les Gones endured a surprising 1-0 defeat to Reims at the Stade de Gerland at the weekend following Odair Fortes's second-half winner.

Grenier had been given the chance to open the scoring from the spot earlier in the half, and he feels that his error cost Lyon a point.

"My penalty miss was the turning point of the match," Grenier told reporters.

"Despite losing at home, it is only at the beginning season and we have a return match Wednesday in the Champions League [against Real Sociedad].

"We cannot talk about a nightmare start to the season right now and we will recover."

Lyon will be looking to overturn a two-goal deficit when they face Sociedad in the return leg of their Champions League qualifier.
