Chelsea keep Andre Villas-Boas waiting for first win

Chelsea's bid to give new coach Andre Villas-Boas a winning start in his first Premier League match was scuppered by some excellent goalkeeping as they drew 0-0 at Stoke City on Sunday.

Following a muted first half, Chelsea picked up the pace after the break with John Obi Mikel, substitute Nicolas Anelka and Salomon Kalou forcing Stoke goalkeeper Asmir Begovic to make some great saves.

Striker Fernando Torres was behind many of the Chelsea moves forward, playing with a confidence last seen in his best Liverpool days, but despite dominating the game last year's league runners-up could not find the back of the net.

As well as being denied by Begovic's acrobatics, in particular when he tipped Mikel's long-range volley over the bar and Anelka's curling shot against the woodwork, Chelsea were also left frustrated that their appeals for penalties kept falling on deaf ears.

Torres was brought down by Stoke defender Ryan Shawcross on the edge of the box early in the second half while midfielder Frank Lampard was caught on the shin by Marc Wilson but referee Mark Halsey did not point to the spot.

Stoke had their own penalty appeal dismissed in the first half after the ball brushed John Terry's arm but otherwise failed to produce much to trouble keeper Petr Cech.

It was a different story at the other end, where Begovic's reflexes were repeatedly tested by a lively second-half Chelsea, inspired by a rejuvenated Torres.

The Spaniard, who scored just one goal in 18 games last season after his 50 million pound ($81.37 million) move from Liverpool in January, had his best chance just before halftime when he surged forward and dribbled past two defenders in the box.

Stoke centre back Shawcross got a foot in to kill off the move but Torres and Chelsea will have been lifted by evidence that the striker's appetite and spark have returned.

"I am only 27, I have not forgotten how to play and how to score and to play well," man-of-the-match Torres told Sky Sports.

"Last season was a season to forget for me ... it's in the past and now I want to look forward."

Fellow striker Didier Drogba, on the bench with Kalou starting instead, came on with 15 minutes to go and sent a free kick straight into Begovic's arms as the keeper made one of the easier saves of his busy afternoon.

Two of Chelsea's title rivals, Arsenal and Liverpool, have also already dropped points with Arsene Wenger's side drawing 0-0 at Newcastle United on Saturday and Kenny Dalglish's men being held 1-1 at home to Sunderland in their opener.

Champions Manchester United start the defence of their title later in the day at West Bromwich Albion, while fellow trophy hopefuls Manchester City kick off their campaign at home to promoted Swansea City on Monday.
