Matthew Taylor fired the hosts ahead when he flipped the ball up and volleyed in before Ricardo Gardner made it 2-0 with another cracking volley.

Peter Crouch headed in at the far post to hand Pompey a lifeline, but they almost conceded again when Rafn Steinsson’s header hit the post.

Kevin Davies had a header cleared off the line as Bolton pressed for a third.

It proved elusive and meant Bolton, who should really have won by a comfortable margin, had to endure an edgy last few minutes.

Bolton took the lead through Johan Elmander’s cute near-post backheel.

But Agbonlahor controlled a long ball before slotting in the equaliser and Villa went ahead when Kevin Davies headed into his own net.

Agbonlahor nodded in a brilliant Young cross and then set up his England team-mate for a deflected finish, before Davies headed a consolation for Bolton.

The hosts could even have had a fifth had referee Lee Probert spotted what looked an obvious penalty claim in the first half but that might have been too much for the Villa Park faithful, who had not seen a league goal since 9 November

The Frenchman put Chelsea ahead when he headed home Jose Bosingwa’s cross after nine minutes, and Deco wrapped up the points with a superb scissors-kick.

The Blues had chances for a third, but Bolton responded valiantly late on.

Gary Cahill wasted their best chance, though, as Chelsea set a new record of 11 straight top-flight away victories.

It surpassed the record set by Tottenham in 1960 and Chelsea will be encouraged by the omens as Spurs went on to win the league in the 1960-61 season.

And Luiz Felipe Scolari will know that if Chelsea can replicate their away form at Stamford Bridge they will be in with a shout come next May, for this was a fine win that keeps up the pressure on leaders Liverpool, who also won.

The hosts had taken an early lead through Djibril Cisse’s classy strike.

But Bolton soon equalised via Matthew Taylor’s header and swiftly stole the lead through Gary Cahill’s low drive.

Woeful defensive errors then let Johan Elmander put away clinical goals either side of half-time as Sunderland fell to their fifth defeat in six league games.

It was Keane’s 100th game in charge of the Black Cats, but many Sunderland supporters left before full-time while boos rang out around the stadium at the final whistle following the club’s third straight home defeat.

Taylor scored with a left-foot strike from the edge of the area that went through a crowd of players.

Marlon King hit the woodwork for Hull while Bolton keeper Jussi Jaaskelainen made a great double save from Geovanni.

The keeper parried from King late on and brilliantly recovered to punch the ball clear with Geovanni again lurking.

David Bentley’s pin-point cross was met by Roman Pavlyuchenko to give Spurs the lead midway through the first half.

After the break, Bolton midfielder Gavin McCann was sent off for two bookable offences.

Darren Bent wrapped up the victory from the penalty spot after he was fouled by Bolton goalkeeper Jussi Jaaskelainen.

The Hammers keeper gifted Bolton their opener when he dropped a hopeful cross at Kevin Davies’ feet and the striker poked the ball into an empty net.

Green then failed to hold the ball after saving Gretar Steinsson’s volley and Gary Cahill was on hand to tap in.

Carlton Cole headed in from a corner to give West Ham hope but Taylor smashed in from 25 yards to secure the win.

Ronaldo put United ahead after referee Rob Styles awarded United a penalty even though Jlloyd Samuel’s tackle on the Portuguese winger was a fair one.

The incident proved decisive because up until then United had been thwarted by Bolton keeper Jussi Jaaskelainen.

Wayne Rooney curled in United’s second after a Ronaldo back-flick as Bolton were left seething over the penalty.

Hungary international Gera put the home side in front as he swept home a half-volley from the edge of the area.

Zamora had a goal ruled out for a foul on Jussi Jaaskelainen, but he made it 2-0 as he turned smartly before burying the ball in for his first Fulham goal.

Gera hit the bar as Fulham looked to be cruising to victory, but Kevin Davies headed in late on for the visitors.

Owen punished the miss when he headed in a Geremi cross at the far post.
