Wesley Fofana made a dream return after seven months out injured as his goal helped Leicester City edge past Rennes and move into the Europa Conference League quarter-finals.
Leicester won the first leg 2-0 at the King Power Stadium but their advantage was halved inside eight minutes when Benjamin Bourigeaud finished from Martin Terrier's low cross.
But 21-year-old central defender Fofana, playing for the first time since breaking a leg in a pre-season friendly against Villarreal in August, then glanced in a header from Ademola Lookman's corner.
The Frenchman ran and hugged boss Brendan Rodgers in emotional scenes, although that was not the last of the goals.
