The Premier League champions, who won the first leg 2-0 in Denmark thanks to Nicolas Anelka’s double, couldn’t turn their domination into goals at Stamford Bridge three weeks later but encountered few problems at the other end to become the third English team to progress, after Tottenham and Manchester United.

Didier Drogba and Anelka, starting up front together with recent 50 million pound signing Fernando Torres on the bench, wasted Chelsea’s best chances in a fairly one-sided match, while John Obi Mikel headed against the crossbar in the second half. 

“The only thing we missed tonight was a goal,” Chelsea manager Carlo Ancelotti said. “But we didn’t need to score—we only have to score a goal when we need to. We didn’t want to take risks. I’m happy with the performance.”

Copenhagen threatened sporadically, although Senegal striker Dame N’Doye hit the post with a first-half free kick.

“The dream would have been if the free kick had gone in,” Copenhagen coach Stale Solbakken said. “It could have changed the game pyschologically. But the better team won (over two legs).”

The Blues reached the last eight for the fourth time in five years but failed to produce many fireworks against the resilient Danish champions. They seem, however, to have recovered from their mid-season blip, and Ancelotti said he fancied the club’s chances of winning its first Champions League title.

“The team is strong enough to win it,” the Italian coach said. “If we play to 100 percent, we can make the final stages. I see my team fresh and we’re in a good moment. But we can improve a lot.”

Drogba’s strength and Anelka’s movement caused Copenhagen’s defense problems in a fairly sterile first half, but it was the visitors who came closest to taking the lead.

N’Doye was kept largely under wraps by Branislav Ivanovic, but the lone striker clipped an effort from a 25-yard set-piece over the wall and against the post with goalkeeper Petr Cech beaten.

“We don’t know how they would have reacted if that had gone in,” Solbakken said.

That was Copenhagen’s only real chance in the whole game, with Chelsea more incisive at the other end until the killer finish was required.

Ashley Cole and Yuri Zhirkov both shot just wide after good work from Drogba, while goalkeeper Johan Wiland produced a smart one-handed save to deny Anelka.

Anelka then set up Zhirkov with a cross across the face of the six-yard box but the Russia international contrived to stroke his effort wide.

With Torres’ introduction imminent, Drogba volleyed wide with the goal gaping in the 48th after a superb cross from Jose Bosingwa, and Anelka lost his bearings when played through twice down the inside-right channel.

With the Blues still in complete control, holding midfielder Mikel headed against the crossbar minutes later, keeping Copenhagen in the series.

Torres, on for Anelka, was given 23 minutes to grab his first goal for the club and sharpen his combination with Drogba.

The Spain striker forced an easy save from Wiland in the 74th but that was the closest he came to ending his drought as the game petered out.

Chelsea will find out on Friday which team it faces in the last eight, but Solbakken said Ancelotti’s side should hold no fear if it is paired with Barcelona, most people’s favorites for the title.

“Barcelona is at this moment a little bit stronger. But Chelsea has a great physique in the team,” said Solbakken, who came up against the Spanish champions in the group stage. “They can outpower Barcelona.”
