Roma close in on knockout stages

An early Kostas Manolas header and Lorenzo Pellegrini's neat finish just before the hour mark gave Roma a win that puts them three points clear of second-placed Real Madrid at the top of Group G ahead of the European champions' clash with Viktoria Plzen later on Wednesday.

Iceland midfielder Arnor Sigurdsson meanwhile was on target for CSKA.

Manolas got Roma off to a flying start when he glanced Pellegrini's fourth-minute corner past CSKA goalkeeper Igor Akinfeev.

CSKA poured forward trying to pull level but the visitors' defence stifled the home team and left them trying fruitless long-range shots.

The hosts had a rare chance to score in the 26th minute when Slovenian midfielder Jaka Bijol met Nikola Vlasic's corner but could only direct his header straight at Roma 'keeper Robin Olsen.

Five minutes later Roma replied with a powerful free-kick by Aleksandar Kolarov, which forced Akinfeev to push the ball to Edin Dzeko, whose attempt on the rebound flashed over the crossbar.

However CSKA came out all guns blazing in the second half and Sigurdsson levelled five minutes after the break, expertly taking a fizzing Ilzat Akhmetov pass under pressure in the area and stroking the ball past Olsen's outstretched hands.

The hosts had their tails up but were reduced to 10 men in the 56th minute Icelandic defender Hordur Magnusson was sent off for his second bookable offence after chopping down lively Roma winger Justin Kluivert.

Pellegrini made them pay just three minutes later when he slipped an offside trap and poked past Akinfeev to help Roma to record three consecutive Champions League wins for the first time since the 2008-09 campaign.

Roma are now five points ahead of third-placed CSKA with two games remaining and can seal qualification against Real Madrid at the Stadio Olimpico later this month.
