Torres troubles continue for Blues
Fernando Torres fired another blank as battling Norwich held Chelsea to a goalless draw at Carrow Road.
The Spain striker, who has not scored since October, endured another frustrating afternoon, denied in the first half by John Ruddy before then stabbing wide in front of goal from eight yards.
Norwich tested Petr Cech through captain Grant Holt and went on to record a first clean sheet of the season as they continued their progress under Paul Lambert.
The Canaries, though, created the first opening on seven minutes as Wales striker Steve Morison got away down the right and fed Anthony Pilkington, whose shot was parried by Cech before Morison's follow-up was blocked by Ramires.
Chelsea responded and Torres collected the ball on the edge of the Norwich area and turned Zak Whitbread before stabbing a shot with the outside of his boot towards the bottom left corner, which Ruddy turned away at full stretch.
There was a stoppage when Frank Lampard needed treatment for a calf injury. The England midfielder eventually was helped off and replaced by Florent Malouda on 36 minutes - just after Bradley Johnson's deflected effort had almost wrong-footed Cech.
Ruddy was out to make a brave take as Torres looked to connect with a right-wing cross into the Norwich six-yard box. It was end-to-end stuff as suddenly Holt got in space on the right and fired in an angled shot which Cech palmed away.
With 58 minutes gone, Torres made space on the edge of the penalty area, only to then blaze the ball over. The Spaniard then somehow managed to stab wide from eight yards after being set up by Jose Bosingwa.
Chelsea continued to press, as Juan Mata's angled shot was saved at the near post by Ruddy. Referee Mark Clattenburg then missed what appeared a clear handball by Raul Meireles on the edge of the Chelsea area when he charged down Holt's flick.
Ashley Cole drove an angled drive across goal and wide from 25 yards as the match entered the closing stages. Norwich dug in to see out three minutes of stoppage time to record their first clean sheet of an impressive Premier League campaign.
