City won the first leg 5-3 at the Etihad.
Iheanacho’s last appearance for Pep Guardiola’s side in the competition was in their last group game against Borussia Monchengladbach, where he scored in their 1-1 draw.
He was an unused substitute for their win against Monaco two weeks ago.
Other players who made the trip included: Raheem Sterling, Kevin De Bruyne, David Silva, Sergio Aguero, Leroy Sane, Bacary Sagna and Aleksandr Kolarov.
Guardiola has vowed to attack the Ligue 1 leaders, despite holding a 2 goal lead.
