Russian league leaders Zenit St Petersburg extended their winning streak to seven matches with a 2-0 success over CSKA Moscow on Friday.
Zenit moved onto 32 points from 13 matches to extend their lead of Moscow clubs Spartak and Lokomotiv to eight points ahead of their games against Anzhi Makhachkala and Amkar Perm on Sunday and Monday respectively.
Midfielder Roman Shirokov put Zenit 1-0 up in the 16th minute when he ran onto Andrei Arshavin's lobbed pass into the area and rounded goalkeeper Sergei Chepchugov before firing home into an unguarded net from a tight angle.
Reigning champions CSKA replied positively and created a host of scoring chances but a lack of accuracy in front of Yury Lodygin's goal let them down.
Brazilian forward Hulk made it 2-0 for the league leaders just before the break shooting into the top right-handed corner from 18 yards. After the interval the hosts controlled the game and their two-goal advantage was never under serious threat.
