Arsenal striker Alexandre Lacazette is backing Lyon to beat St Etienne in this weekend's derby.
Lacazette is confident his former club will be too strong for ASSE.
He said, "This season, 'we' are able... OL is able ... to make very great performances as against Manchester City and at the same time to miss some matches. This is probably due to the lack of experience of the team.
"We know that at the highest level, the smallest details have their importance on the final result. To win, OL will have to be focused because Saint-Etienne is pretty well armed: they have made a smart recruitment by bringing players of quality experience.
"This derby will also be a great rehearsal before the Champions League match against Manchester City."
