Barcelona fullback Hector Bellerin says the players felt they deserved more from their Champions League campaign.
Barca have failed to reach the round of 16 as they face Viktora Plzen tonight.
Bellerin said, "We are disappointed. We believe we deserved more in many situations.
"As a team we are aware of the quality we have and we are showing it in the league. In football we cannot continue to look to the past. We are Barça and we have the obligation to be at a good level in the four competitions we have left.
"There have been injustices, but we cannot apologise at all. As players and as a team we must take responsibility for elimination."
