The pair were heavily linked with moves away from Les Gones over the summer but failed to secure a transfer.
However, Garde now insists that he will be prepared to use both players after they failed to exit the Stade de Gerland.
"Everything went fine after an episode that dragged on and on," Garde said in a press conference.
"We spoke before training but that will remain between them and me. They are 100% ready, in the squad and available to me. I have no doubt as to their motivation."
Gomis and Briand are both out of contract at Lyon at the end of the season.
