The France international says a goal against the Ligue 1 side would be extra special considering his history with Lyon
Manchester United forward Anthony Martial is desperate to strike against Saint-Etienne, a side he has always seen as a rival, in the Europa League.
Martial started his club career at Lyon, with whom Saint-Etienne play the fiercely-contested Rhone-Alpes derby.
The France international did not get the chance to play in one of those games, but did strike against Thursday's opponents while at former club Monaco.
United are at home for the first leg of the last-32 tie and Martial, who netted in the Premier League win over Watford on Saturday, is eager to haunt Saint-Etienne again.
