Marseille defender Rod Fanni was left angered by what he felt was an undeserved red card in the 2-0 defeat to Paris Saint-Germain in the last 16 of the Coupe de la Ligue.
The right-back was sent off midway through the first half of Wednesday night's tie at the Parc des Princes for a foul on PSG's Guillaume Hoarau, with defender Thiago Silva scoring the subsequent penalty.
Jeremy Menez doubled the lead for Carlo Ancelotti's side to send Les Parisiens into the quarter-finals at the expense of the holders.
After the match, Fanni expressed his disappointment at the decision to send him off and claimed Hoarau had deceived the officials.
''Hoarau pretended there was a foul, he was not completely off balance," he said. "I'm really disappointed to let down my team-mates, I don't think it was deserved.
"In any case, it happened outside the box. This penalty was not justified. But to err is human. I ask myself a lot of questions tonight [Wednesday night]. At 11 against 11, the game could have been different."
Marseille coach Elie Baup echoed Fanni's sentiments, insisting that the incident should not have led to a spot-kick.
''I learnt something, a foul outside the box can be punished with a penalty," he said. "The foul was committed outside the box and finished inside.
"With ten players it was obviously more difficult. Even if we were aware it was unfair, we tried to get a result, with plenty of effort. The problem wasn't (injured striker Andre-Pierre) Gignac's absence, but we played at 12 against 10."
