Chelsea maintained their 100 percent record in Group H with a hard-fought 2-0 win over CSKA Moscow.

First half goals from John Terry and Eidur Gudjohnsen were enough to give Chelsea another three points and move them a step closer to the knock-out stages.

CSKA Moscow started brightly with Terry getting in a vital block to deny Wagner Love a shot on goal and Daniel Carvalho saw a deflected shot pushed round the post by Petr Cech.

Chelsea broke the deadlock on nine minutes with their first real chance of the game through Terry.

CSKA goalkeeper Igor Akineev came out and flapped at Frank Lampard's corner allowing Eidur Gudjohnsen to head the ball down into the path of Terry to nod home into the unguarded net from four yards out.

Lampard had a half chance for Chelsea on 12 minutes when he picked the ball up on the edge of the area, but he fired his left-footed shot well wide of the target.

Paulo Ferreira got in a vital block on 20 minutes to deny Sergei Semak a shot on goal after he found space inside the box.

The visitors suffered a blow on 24 minutes when Carvalho was forced off injured and had to be replaced by Juris Laizans.

Moscow were dominating possession and Sergei Ignashevich forced Cech into a good save on 34 minutes with a powerfully struck free kick from fully 30 yards which the keeper did well to push away.

Terry went close to grabbing his second goal of the night on 38 minutes when he got on the end of Lampard's free kick and flashed his diving header just wide of the target.

Cech maintained Chelsea's lead three minutes before the break with a brilliant reflex save to tip over a wicked deflection from Gudjohnsen after a dangerous corner into the box from CSKA.

Chelsea doubled their lead right on the stroke of half time when Gudjohnsen rose unmarked inside the box to head home Lampard's free kick.

CSKA continued to produce some neat attacking approach play in the second half without really troubling the Chelsea rearguard.

Yevgeny Aldonin tried his luck from long-range on 56 minutes and his shot was well saved by Cech.

Alexei Smertin broke through the CSKA ranks on 68 minutes running on to Gudjohnsen's fine pass, but he wasted the opening by over-hitting his cross beyond the unmarked Damien Duff inside the box.

The second half was very much a lacklustre affair with Chelsea content to keep possession and defend their comfortable lead.
