Mikel Arteta admits Arsenal's form of late has been "unacceptable".
The Gunners have been defeated in crucial games against Blackburn, Bayern Munich and Tottenham recently, leaving them on the verge of an 8th successive trophy-less season and in danger of missing out on Champions League qualification.
Arsenal are 3-1 down from the first leg of their last-16 Champions League tie against Bayern Munich and face an uphill task if they are to turn things around in the second leg at the Allianz Arena tomorrow.
Arteta says the fact that Arsenal are well out of the title race with 10 games to go and are also trailing rivals Tottenham by seven points following their defeat at White Hart Lane last nine days ago in the race for Champions League qualification isn't good enough.
"With 10 games to go and to be 24 points behind [Manchester United], it's an impossible catch and that, for me, is unacceptable," Arteta told the Daily Mail.
"We can't be in that position because we have the best basic structure I've ever seen at a football club. Great philosophy, good players, we've got financial backing to do whatever we want, unbelievable crowds for the stadium. Let's go for it!
"Staying in the Champions League is massive. If we don't get in those spots it makes everything much more difficult. To any team with top players, you have to ask what's going to happen. There's only one answer: we want to improve the team.
"We want to be better and next season we want to get more points, which means we will have won more games. I think the board know that and, hopefully, this summer we'll do something about it."
Arteta got his first taste of Champions League football with Arsenal having made the switch from Everton to the Emirates Stadium in 2011, and the Spaniard says playing in Europe's top tier club competition is a motivating factor for him.
"To play in those big games is a great experience and I don't regret the decision. It improves you as a player.
"It's a good test to see where you are. Sometimes you think you are playing unbelievable but then you play in the Champions League against top players and you think: 'I've got a lot of work to do'."
Arsenal's hopes of pulling off a dramatic turnaround against Bayern tomorrow were dealt a blow when it was revealed Jack Wilshere will be out for three weeks with an ankle injury.
