Arsene Wenger insists Arsenal will win the Premier League if they remain unbeaten for the rest of the season.
The Gunners head into 'Grand Slam' Sunday - when the top four all go head to head - having seen a lead clawed back and then overtaken by Manchester United as their form stuttered.
However, despite four consecutive draws, Wenger insists his men are in good shape heading into the run-in.
'I feel that since the beginning of the season we have been the most consistent team,' the Arsenal manager declared.
'We have lost just one game, and that was under very special circumstances, so that consistency will come out for good at the end of the season.
'If we win our big games and if we continue to be consistent then I am sure we will finish in front of the other sides.
'I cannot imagine we will lose the league if we have lost only one game at the end of the season.'
The Arsenal manager insisted: 'We have got the strength of character to win the title, believe me.
'That is my firm belief and at the game on Sunday you
'Since the first day of the season I have said that I believe in this team, come back in May and we will speak about it then.
'There's always a first time and until you win people have doubts about you, they're questioning you - but the strong ones keep going.'
Following last weekend's results, when Arsenal scraped a 1-1 draw at home to Middlesbrough, Wenger conceded some of the belief within his squad had faded as he surveyed a deflated dressing room.
However, the Arsenal manager insists the reaction this week has reinvigorated everyone for the battles ahead.
Wenger continued: 'I believe that we had a little slow down after Birmingham (when they drew 2-2 and Eduardo da Silva was badly hurt), but I feel now in training that we're over that.
'This is a good opportunity for us to show that.
'On 'Grand Slam' Sunday all four teams have a very good reason to try and win the game.
'When we go into this game, we'll know the result of the United game against Liverpool - that could even increase more the pressure on the game.
'But the mental strength we have in my squad, and the hunger that's in there for us to do well, I'm sure will come out in the final sprint.'
While United won their game in hand against Bolton on Wednesday night to move three points clear at the top, Chelsea failed to close up on Arsenal after they drew 4-4 at Tottenham despite having led 3-1.
Wenger watched the tape of the Spurs game, which he noted was 'kind of crazy in the last 20 minutes and got out of control'.
The Arsenal manager is, though, anticipating a stern examination of his side's title credentials when they take on the Blues.
He said: 'I expect them to play well against us, and I think we will win the game if we play well.
'Let's focus on us, to be at our best again, on us winning the game, and not expect any weakness of Chelsea.'
Wenger, though, accepts the championship will not be settled one way or another come Sunday night, as there remain key clashes between Chelsea, United and Arsenal still to come.
He said: 'We know the outcome of the championship will be down to the direct confrontations between the top teams.
'Chelsea will not be completely out of it if they lose, but of course it would be a blow to them.'
Wenger could yet opt to give young forward Theo Walcott a start at Stamford Bridge.
The 19-year-old former Southampton trainee was called into Fabio Capello's England squad for the first time, having not featured since his controversial inclusion at the World Cup in 2006.
Wenger said: 'I am very pleased with Theo.
'He had a very easy start, with the red carpet from the start. Then he got knocked out again but now he has come back very firmly and that is on merit.
'He is on his way up again and very soon he will be a major player at this club.
'It is a big decision on whether to start him on Sunday, but that is part of this being a big game.'
