Manuel Almunia believes Arsenal must win all six of their remaining Premier League games if they are to take the title.
The Gunners have been fighting to make up ground on Manchester United and Chelsea for much of the campaign and they still occupy third place with just a few weeks to go.
Arsene Wenger's men currently trail leaders United by four points and are three adrift of Chelsea, with the top two meeting at Old Trafford this Saturday.
Almunia does not expect United or the Blues to drop many points after this weekend's clash and feels Arsenal must enjoy a perfect run-in if they are to have any chance of domestic glory.
"We have six games left now and we must record six victories," said the Spanish goalkeeper.
"We'll have to wait to see if Manchester United drop points as well but we still have a chance of winning it.
"We just have to win our six games and see what happens."
Almunia responded to recent criticism of his form with a fine game in the first leg of Arsenal's UEFA Champions League quarter-final against Barcelona on Wednesday night.
The 32-year-old was beaten twice in a 2-2 draw but he pulled off several important saves to help keep the Gunners in the tie, although he was at fault for the Spanish side's opener.
"It was my busiest game for Arsenal," he said. "They created a lot of chances and it was hard but we showed a lot of spirit in the last 20 minutes and we battled back to get a draw.
"With it being 2-2 we have a lot better chance of getting through than we did when it was 2-0. But we'll have to change a bit and show more character and creativity and not give Barcelona the ball as much because when they get the ball they play good football and create many chances."
Theo Walcott's introduction prompted a shift in momentum as Arsenal battled back from 2-0 down and Thomas Vermaelen has tipped the winger to play a key role at Camp Nou in the return leg.
"Theo was very dangerous for us when he came on," said the Belgium defender.
"At the end of the game we were physically a lot stronger than them and I think they were a little bit tired and with Theo's pace you can create a little bit of danger and that's what he did."
