Interim Everton manager David Unsworth was left irritated by his team's mentality during Thursday's 3-0 defeat at Lyon, telling them they cannot "cave in".
The loss in France confirmed Everton's elimination from the Europa League despite still having two Group E matches to play.
They managed to keep things level until half-time, but goals from Bertrand Traore, Houssem Aouar and Memphis Depay in the second period rounded off a miserable day for Everton, who saw Morgan Schneiderlin sent off and Cuco Martina taken to hospital after a nasty fall.
