Lazio coach Simone Inzaghi admits he expected more from his players after their Europa League win over Apollon Limassol.
Luis Alberto and a Ciro Immobile struck the goals for Lazio.
"The regret is that we didn't score at least one more goal and that Apollon found the net with a lucky ricochet," Inzaghi told Sky Sport Italia.
“We wanted to begin the group with a victory and we achieved that. I liked the initial approach to the game, which was the first for many of our players, although in the second half we could and should have done better.
“It won't be an easy group, as Eintracht Frankfurt proved themselves a good team, just like Marseille."
