Manchester United manager Sir Alex Ferguson admitted his players could 'taste' the Premiership title after they came from behind to maintain their six-point lead with a 4-1 win over Blackburn.
Matt Derbyshire's prodded goal just before the half-hour mark had given Rovers a half-time lead and threatened to provide an expected twist to the title race before the home side turned on the style after the break.
Paul Scholes fired the equaliser past Brad Friedel before Michael Carrick, Park Ji-Sung and Ole Gunnar Solskjaer wrapped up victory.
The only setback was a shoulder injury to Nemanja Vidic which will keep him out for a month.
Ferguson said: 'The second-half performance was our best of the season. It was the kind of performance you expect from a championship team.
'I think the fans are starting to smell it now - and the players are beginning to taste it.'
Salomon Kalou's header deep into injury time kept Chelsea clinging on with a 1-0 win at rock-bottom Watford.
But Jose Mourinho admits they can afford no slip-ups if they are to keep their hopes of overhauling United intact.
Despite winning their last seven Premiership matches the Londoners have failed to dent United's lead - but Mourinho still maintains it is possible for United to drop the required number of points.
He said: 'We have won every game in every competition in March. Now we have to do the same in April.
'We cannot afford to lose any match in any competition. I still absolutely believe that United can drop six points.'
Peter Crouch returned from a broken nose to hit a hat-trick as Liverpool moved above Arsenal into third place with an emphatic 4-1 win over the Gunners at Anfield.
Crouch put the home side 2-0 ahead at the interval before Daniel Agger added a third.
William Gallas hit a consolation for Arsene Wenger's men before Crouch completed his hat-trick 10 minutes from time.
The battle to avoid relegation continued to heat up with Alan Pardew's Charlton taking advantage of a controversial penalty to overcome fellow strugglers Wigan and move within a single point of safety.
Darren Bent fired home from the spot four minutes from time after Wigan defender Fitz Hall had been rather harshly adjudged to have fouled home defender Hermann Hreidarsson.
Pardew said: 'This was a big, big win for us. We have Sheffield United to play at home and we are now in control of our own destiny, and we couldn't have asked for that two months ago.'
Neil Warnock's Sheffield United now look the most likely side to fall foul of Charlton's revival, as they fell to a Kevin Davies goal at Bolton, who themselves reignited their UEFA Cup ambitions after three consecutive defeats.
West Ham also did their survival hopes the power of good with a second consecutive win - goals from Bobby Zamora and Carlos Tevez seeing off Middlesbrough at Upton Park.
Boss Alan Curbishley said: 'What we have done is get ourselves back on track but all we can do is win the majority of our games.
'We are looking at other results but we have got to get them ourselves first.'
Manchester City all but banished their own relegation fears with Emile Mpenza's 81st-minute winner over Newcastle at St James' Park, while Ian Pearce hit a late equaliser to give Fulham a 1-1 draw with Portsmouth at Craven Cottage.
In Sunday's action, Tottenham moved up to sixth place after a 1-0 win over Reading, with Robbie Keane netting the only goal of the game from the penalty spot after Greg Halford had been penalised for handball.
