January signing Gary Cahill has stressed that Chelsea must believe in themselves if they are to claim a top four finish this season.
Qualification for the Champions League will change the complexion of a disappointing season for the West London side, with The Blues still in the later stages of two cup competitions.
Cahill, 26, has found himself a regular first-choice since interim boss Roberto Di Matteo took command and believes the club can still achieve success this campaign.
"We have to be confident. Our form of late's been good," said England centre-back Cahill.
"Obviously, we've got to win basically the majority of the games we've got left and we've got some tough games coming up. That's our target, that's what we're aiming for.'
"Everyone was saying how a bad a season it was. But we we're in a quarter-final, we're in a semi-final and we've still got a chance to push for that fourth spot.
"So, it's going to be a massively important period coming up for us, the end of the season.''
During Saturday's encounter with Spurs, Cahill rescued his side with a superb goal-saving tackle on Emmanuel Adebayor to make amends for an earlier mistake and believes he is now showing Chelsea fans his best form.
"I was disappointed earlier on with my decision to step up,'' said the 26-year-old, who had scored in his two previous games.
"So, to rectify that and to get back in, it's as good as a goal for me. I'm happy with how things are going at the minute."
"To try to settle in and play straight away to the standards that I expect from myself is tough and it took me a couple of weeks.
"But now, the last few weeks - as hopefully you've seen - I'm back to where I should be and I need to maintain that."
