Reigning champions CSKA Moscow battled back from a goal down to win 2-1 at struggling Tom Tomsk on Saturday and go clear at the top of the Russian Premier League.
The Red Army side have won four and drawn two of their opening six games and sit one point clear of second-placed Rostov, who face Lokomotiv Moscow on Monday.
Spartak Moscow, who take on Amkar Perm also on Monday, share third place with Zenit St. Petersburg, who drew 1-1 with Dynamo Moscow.
CSKA trailed 1-0 when Tomsk striker Igor Portnyagin converted the rebound from close range just before the half-hour mark after the Red Army side's goalkeeper Igor Akinfeev had stopped Kirill Panchenko's initial effort.
The capital club drew level in the 52nd minute when Côte d'Ivoire forward Seydou Doumbia headed home a cross from the left from Georgy Shchennikov, and Nigeria forward Ahmed Musa then got the winner seven minutes later.
He finished into an empty net after Tomsk goalkeeper Petr Vasek had parried Zoran Tosic's shot from just inside the area.
"In the first half, we lacked passion, but after the interval we used the wide areas a lot more and it paid off," CSKA coach Leonid Slutsky said.
Kerzhakov saves Zenit in injury time
After a goalless first period at the Khimki Arena, Dynamo Moscow grabbed the lead in the 64th minute against Zenit when Hungarian winger Balasz Dzsudzsak's shot found the net with the help of a ricochet.
However, Zenit rescued a point when substitute Alexander Kerzhakov headed home from close range in the third minute of injury time, leaving their Russian coach Luciano Spalletti satisfied.
"Of course it's a good result for us," Spalletti said. "It was a really hard match on a rain-soaked pitch.
"Dynamo played well, while we were a little tired after Tuesday's Champions League match," he added in reference to the 4-1 win away to Pacos de Ferreira in Portugal that left Zenit on the brink of qualifying for the group stage.
In contrast, Dynamo coach Dan Petrescu was frustrated at his side's inability to hold on for the win.
"We were the better side today but Zenit managed to convert their only serious chance of the match," he said.
"We controlled the game and created more chances but unfortunately the better side doesn't always win."
Anzhi still winless
Meanwhile, Anzhi Makhachkala, who have already lost several players after billionaire owner Suleiman Kerimov decided to drastically cut the side's budget and scale down their ambitions, are still winless.
They suffered a 2-1 home defeat at the hands of FC Krasnodar on Saturday and have just two points after six games.
Uzbek midfielder Odil Akhmedov put Anzhi 1-0 up just before the break but Brazilians Mauricio Pereyra and Francisco Wanderson both struck after the interval to give the visitors their second win of the campaign.
