Olivier Giroud has told Arsenal fans not to forget everything that manager Arsene Wenger has done for the club.
The Gunners secured their place in the Champions League round of 16 for a 15th consecutive year with a 4-1 win at Galatasaray on Tuesday, and Giroud said Wenger was still a "great manager."
Wenger has been the focus of supporter discontent amid a stuttering Premier League campaign.
He was subjected to verbal abuse from his own supporters following the 3-2 loss at Stoke last weekend, a result that left Arsenal 13 points behind Premier League leaders Chelsea.
"I understand the fans because, when you are a team like Arsenal, the fans want you to win every single game, especially when they follow you to away games,'' Giroud told PA Sport.
"It's always like that when you suffer a defeat. I understand the fans are really disappointed, but we are very disappointed as well.
"It is not the manager [who is to blame]. He is a great manager. Just because we lost at Stoke in an away game, it does not mean the season is finished or that everything is over.
"They have to remember what the manager has brought to the club. There is no other coach who knows Arsenal better than him, so I am in no doubt he is the man to solve this situation."
Arsenal, who were a goal down within a minute at Stoke and 3-0 behind at half-time, were booed off by their travelling supporters at the end.
The team's defensive frailties were again exposed at the Britannia Stadium, but Giroud said: "When we concede goals it is not just the defenders, it is all about the whole team -- we have to defend better together, I think.
"When you watch the way Stoke play, you need to be ready from the start -- and we were not in the game straight away, so if you then make small mistakes you pay the price.
"Commitment and determination in individuals are things you cannot forget in football. We didn't do well in the first half and being 3-0 down was tough at half-time. We came back very well in the second half, but it was not enough."
Wenger's Gunners will be looking to get their domestic campaign back on course when they host rejuvenated Newcastle on Saturday.
The Magpies inflicted a first defeat of the campaign on Chelsea last weekend, and a run of only one defeat in nine games has drawn Alan Pardew's side level on points with Arsenal.
"We need to bounce back," Giroud, who scored in both meetings between the teams last season, said.
"We know our quality and we know what we can do. We will show our strength of character against Newcastle at home."
The striker said he did not accept that Champions League qualification was the best the Gunners could hope for in May.
"Chelsea were 13 points ahead before the game last weekend, and we are still 13 points behind them,'' he explained.
"Chelsea will not win every game -- we are going to take games one by one and focus on ourselves.
"If we don't lose, we don't have to look at Chelsea's results. We just need some momentum, some more wins and to get our confidence back."
