Only a miracle will save Arsenal from completing a sixth successive season without any silverware, but Switzerland international Djourou believes everything is about to fall into place.
Djourou, the club's longest serving player having joined the club in August 2003, told the Guardian: "The Invincibles team of 2003-04 had great players but what people forget is that before that similar questions were asked about them.
"So for us it's just a matter of 'let's win' and then the opinion will change. I don't think it's a massive difference because we have the same qualities and maybe better qualities than the unbeaten team. I'm not going to compare the two. I am just saying that we are not far short.
"When the club signed Thierry Henry, he hadn't even been playing at Juventus, the same with Patrick Vieira at Milan while Freddie Ljungberg came from a little Swedish club. But look at what they became. People have to remember that it's a foundation of work and not everything works as soon as they want.
"The Invincibles team was a project that was not made in one year. It was piece by piece by piece. We have to keep the faith in this project and we just want to win to show the world that the boss is right. It takes a lot of courage to keep going with your own way.
"I don't see Man U as being better than us this year. They have just been more consistent. Quality-wise, I don't see a better team than us."
The Gunners have won just two matches, against Leyton Orient and Blackpool, since their Carling Cup final defeat to Birmingham City, and Djourou concedes the match has been hard to forget for the squad.
"On the day it looked like Birmingham wanted it more than us," he said. "Why? I don't know. That's a good question. Maybe, the occasion for them was different. The defeat was a big blow because when you are in a final all you have in your head is to win. You put yourself in a winning position but, when you realise you've lost, it is a massive kick. You think it's the end of the world. The result had a massive impact on us."
