Arsenal midfielder Emmanuel Eboue has admitted that supporters are entitled to vent their frustration.
Eboue had to be substituted in the Premier League match against Wigan earlier this month after a section of the Emirates Stadium crowd started to boo him.
The Ivory Coast international, who had only been introduced from the bench earlier in the game, had been playing poorly and does not blame the fans for being critical.
He was disappointed with the reaction but hopes to learn from the experience and improve as a player, starting with Sunday's crunch clash against leaders Liverpool, live on Sky Sports 1 and HD1.
"I do not know why the fans did not back me, but that is football and you cannot do anything about it," Eboue told Arsenal TV Online.
"They pay money to watch Arsenal win. Then when we do not play well, not give our best performances on the pitch, they are very angry.
"I do not blame them, and I hope they will all come out to support us on Sunday, when we will try to do our best and try to win the game for them.
"I try to forget that now. I was disappointed, but I am happy now.
"After the game, my friends gave me a ring and helped me a lot. The next day in training, I saw the boss and he gave me confidence."
Travelling supporters chanted Eboue's name before the UEFA Champions League game against Porto four days after the Wigan match, and the 25-year-old later threw his shirt into the crowd in appreciation.
He explained: "Before the Porto match, I said to myself I was going to do that for the fans because they know me, they know I can give more for the team.
"When we went there, I was very happy because the fans were singing my name - that made me really happy and gave me more power on the pitch.
"At the moment I am not at my best performances, but I try to give more and do my best when the boss puts me on the pitch.
"If I continue to work hard in training, then I am confident I can get to my best."
