Chelsea slipped to fourth place in the Barclays Premier League as a goalless draw against Hull meant they have dropped 16 points at Stamford Bridge this season.

The Blues are three points behind Aston Villa and their chances of catching title favourites Manchester United are fading fast.

Chelsea face Watford in the FA Cup next weekend, then travel to Villa in the league before a first leg tie against Juventus in the last 16 of the Champions League at Stamford Bridge.

The Blues felt the frustration of Chelsea's fans against Hull as they taunted Scolari with chants of 'You don't know what you're doing' before booing them off at the end of the game.

Assistant coach Ray Wilkins labelled the minority as being 'out of order' but an FA Cup and Champions League exit could put an end to a disappointing first season under Scolari.

Terry, though, is determined to lead the Blues back into the title race and delivered another rallying call.

"The challenge is massive," said Terry. "We can't take our focus off it for one minute. We have to win something this season.

"We have to do everything we can to get ourselves back in the thick of the title race.

"We have to start winning and keep on winning. We have to win big games like Villa and Arsenal away and Watford next week.

"What is important is that we all stick together and that's the supporters as well."

Chelsea have kept just one clean sheet against their four rivals at the top of the table and Terry accepts that is not good enough.

They have failed to beat Manchester United, Arsenal, and Liverpool but managed a 2-0 success over Villa back in October.

"In games against the top five we've only kept one clean sheet this season, the win over Aston Villa, and that's not good enough.

"We haven't scored enough goals against them either."

Scolari may have been the target for a section of the Chelsea boo boys but there is no doubting his desire to push their title rivals all the way - despite the gap in points.

Scolari said: "We are prepared to fight and we are aware that there are many points still to play for and for the teams above us to drop - it is only February and the league ends in May.

"We want to take our battle for the title right to the end of the season."

Chelsea were unable to overcome a stubborn Hull side, who squandered a couple of chances to win the game themselves, and even winger Ricardo Quaresma, on loan from Inter Milan, failed to inspire them.

It was his substitution in favour of Didier Drogba, in the second half, that sparked the chants from the boo boys but Wilkins backs Scolari to cope with the pressure.

"Whenever someone manages at a club as big as Chelsea there is always pressure to bring home trophies that is not only here but at Arsenal, Man Utd and Liverpool," said Wilkins.

"And to a large degree the guys at the bottom end of the table face pressure to keep teams in the division.

"There will always be that type of pressure to win trophies and he will strive for that and we will work extremely hard to try and achieve that goal."
