The 29-year-old French full-back has issued a rallying call to his Gunners teammates in the face of adversity, after disappointing defeats against AC Milan in the Champions League, shortly followed by another loss at the Stadium of Light on Saturday.
Sagna has urged the players to bounce back positively by ensuring there is no repeat performance in the north London derby when Spurs arrive at the Emirates Stadium this weekend.
"We have to keep our heads up, work hard and think about the Premier League because we have a derby next weekend against Tottenham," he told Arsenal Player.
"We need to do it for us and for the fans as well. We have to react. We can't play like this against Tottenham otherwise we will lose.
"We have one week to get ready for the game, to question ourselves, to work and to talk to each other. We are professional and we have to fight until the end. Personally I want to do it and everyone else wants to do it as well."
Despite the recent disappointments, Arsenal can always count on the unwavering support of their travelling fans, and so good was their backing in the last two encounters on their travels that Sagna says the players owe them a performance on Sunday.
Last time out against Tottenham, Arsene Wenger's side were condemned to a 2-1 defeat at White Hart Lane thanks to a Kyle Walker wonder strike, so the Gunners will be looking to get their own back at home this time around.
"We just want to thank them one more time even if we didn't get the result," he added. "It is not easy for us and for them as well.
"We are just thankful for the support that they give us and we'll try to win next weekend. We have to look forwards. We are fourth in the Premier League and we can't let it go like this."
