Antonio Valencia struck a late winner as Manchester United maintained their 100% record in Champions League Group B with a 1-0 win over CSKA Moscow.

Chances had been at a premium on the artificial surface of the Luzhniki Stadium - scene of United's final victory in 2008 - but United finished strongly.

Valencia, who celebrated his first United goal last weekend, doubled his tally for the club five minutes from time, moments after rattling the crossbar with a fierce drive.

United began to assert themselves more midway through the first half and O'Shea had a cross headed clear by Sergei Ignashevich.

Nani again broke clear for United before the break but Gary Neville shot over after the ball worked its way across goal.

The second half got off to a lively start with chances at both ends. Nani raced through from a Valencia backheel only to find no-one with his cross while Berbatov controlled well but saw his shot blocked.

Necid then brought down the ball brilliantly outside the United box but after doing the hard work, his shot was tame.

Michael Owen was introduced as a 71st-minute substitute for Scholes and had a fine opportunity when Valencia crossed five minutes later but he failed to connect with a volley.

Valencia went much closer eight minutes from time when he combined well with Berbatov and Nani on the edge of the area but his powerful shot rebounded off the woodwork.

Not to be denied, Valencia went one better five minutes from time when he latched onto a downward header from Berbatov and turned six yards out to lash in the winner.
