Villa have had an offer for Traore accepted by OL, with the forward passing a medical yesterday.
Sky Sports says Traore will join Villa for an initial fee of £17m with another €2m due to OL in bonuses.
For the 2019/20 season, Traore played 35 matches for Lyon, scoring 4 goals and producing 5 assists.
A move to Villa will mean a return to England for the former Chelsea youth teamer.
