Blues keep Barca at bay
Chelsea secured a superb first-leg goalless draw against free-scoring Barcelona thanks to a dogged defensive display at the Nou Camp.
Barcelona were thwarted time and again by goalkeeper Petr Cech who saved superbly to deny Thierry Henry and Alexander Hleb.
But Chelsea striker Didier Drogba wasted a vital chance in the first half while substitute Bojan Krkic headed over the crossbar from point-blank range for Barca in the final minute.
The hosts almost grabbed an early lead when a free-kick from the left reached Samuel Eto'o at the far post after Cech misread the flight of the ball. However, the Cameroon striker's far-post header flashed across the face of the goal with Rafael Marquez unable to connect.
In the 28th minute Xavi almost broke the deadlock with a long-range drive that flashed past Cech's right-hand upright.
But Chelsea should have been ahead when a dreadful back pass by Marquez put Didier Drogba clear in the 38th minute but the Ivorian's shot was twice saved superbly by Barca goalkeeper Victor Valdes.
Chelsea's defending had been admirable from the kick-off and Guus Hiddink's side showed no sign of capitulating. Whenever the home side did break through they found Cech in their way. In the 61st minute he proved his worth yet again when he blocked a ferocious angled drive from Alves.
In the 67th minute the former Sevilla star sent a free-kick just over the crossbar and Cech denied Eto'o with a fabulous save when the Barca striker got free of Alex for the first time in the game in the 69th minute.
Substitue Carles Puyol, who came on for the injured Rafael Marquez, was booked for a foul on Michael Essien in the 75th minute and the card rules him out of the return leg at Stamford Bridge.
But Bojan could have won the first leg for his side but he somehow headed a cross from Alves over the bar from point-blank range, and there was still time for fellow sub Alexander Hleb to be denied by another great save from Cech in stoppage time.
