Gallas has found himself coming in for criticism following his reaction to the last-gasp draw at Birmingham on February 23 when he broke down in the centre-circle, as well as a controversial magazine article commenting on Theo Walcott's development.
Manager Arsene Wenger, though, maintains the 30-year-old is the right man to lead his young Gunners forward.
"Now I have to give everything until the end, so the season is not finished yet. We will see at the end."
Gallas added: "I will be happy at the end of the season if we win something. That is my job.
"We know it will be maybe more difficult in the Premier League, we have to win every game and that will not be easy."
