Lyon have confirmed the transfer of 21-year-old central midfielder Timothé Cognat to Swiss side Servette on a permanent deal.
The move follows a successful loan spell at the latter outfit in 2018/19.
Cognat joined OL in 2001 and has played for France at U17 youth category level. He signed his first professional contract with Lyon in 2018, before spending the most recent campaign in Geneva, where he played 35 games out of a possible 36 in a spell that won Servette the Swiss 2nd division.
The fee involved is understood to have been negligible.
