Arsene Wenger believes Arsenal have the hunger and mental strength to challenge for the Premier League title this season.
The Gunners were written off in some quarters after their defeat at home to Chelsea in late November left them 11 points off the pace.
But they have battled back into contention, helped by the inconsistent form of their rivals, and will climb to within a point of the summit with a win over Bolton on Wednesday evening.
Wenger maintains that he never lost faith in his players and he is proud of the way they have shown their character.
"We have a good opportunity to come back very close to Chelsea, and we want to take it, to make it more interesting for everybody," he said.
"One month ago we were far from the top teams, and since have created momentum.
"We refused to give up and continued to fight and believe in our strengths.
"The biggest test in our camp was the mental strengths of the players and the solidarity of the players. That has been tested.
"What we have realised in one month gives us a good springboard to go even further. Why should we stop here?
"The next two months will determine how ambitious and how hungry we are."
Wenger believes the fact that most of his young players have stayed together through their development has helped to cultivate a strong spirit at Emirates Stadium.
He added: "It does not mean Chelsea or Manchester United do not have hunger - but what I know is that within our team we have a great hunger for success. We have great solidarity and team spirit.
"We are a team who has grown up together and wants to achieve things.
"We have not won anything yet together and that makes us hungry for success."
Meanwhile, Wenger is happy to be welcoming Denilson back into his side for the clash with Bolton.
The versatile Brazilian is fit again following a back problem and will replace the more defensive Alex Song, who has left for the African Cup of Nations.
"Denilson is an all-rounder, but he can play in this position and will come in for Song," said the Arsenal boss.
"He is very strong in reading the game and winning the ball back.
"Denilson has 150 games in the Premier League. People do not notice how important he is for us and he can play in every single position in midfield."
