Sagna is still confident of securing Champions League football and says the team must quickly turn its attentions to Stoke on Saturday.
"I think against Chelsea we struggled to pass the ball as we are used to. We weren't with the ball as much and we struggled to create chances," Sagna told Arsenal Player. "But at least we did not lose and we kept a clean sheet so we have to look forward to the next game.
"We want to qualify [for the Champions League] and we want to finish third. It won't be easy but we want to do it.
"Everyone wants to qualify for the Champions League. We have Tottenham behind us, Newcastle are not far away. It will be down to us, we have our destiny in our own hands."
