Defending Russian Premier League champions CSKA Moscow suffered their first defeat of the new season, losing 1-0 to Spartak Moscow.
Spartak emerged victorious from a fiery derby in the capital, Dmitri Kombarov s penalty in the 61st minute settling the game in the visitors favour, before CSKA s Kirill Nababkin and Spartak s Sergei Parshivlyuk each saw red in the third minute of injury time.
CSKA s defeat means Zenit are the only team in the league with a 100 per cent record, although Andre Villas-Boas men needed a 31st-minute penalty from Hulk to seal a 1-0 win over newly promoted Ufa, as they attempt to regain the title they last won in 2011-12.
Dinamo Moscow leapfrogged CSKA into second with a 2-1 victory at Arsenal Tula, Douglas and Kevin Kuranyi on target in the first half before Ivan Ershov gave Arsenal false hope with a 47th-minute strike.
Rubin Kazan are still without a win after they played out a 1-1 home draw with Lokomotiv Moscow, Gokdeniz Karadeniz s 31st-minute penalty earning the hosts a share of the spoils after Aleksey Miranchuk had put Lokomotiv ahead five minutes earlier.
Torpedo Moscow claimed their first win of the campaign with a 2-0 success at Ural, while Krasnodar came away from their trip to Rostov with a victory by the same scoreline.
Elsewhere, Romanian attacker Gheorghe Bucur scored in the second minute of injury time to give Kuban Krasnodar a 1-0 triumph over 10-man Amkar Perm, who saw Fegor Ogude sent off, and Terek Grozny beat Mordovia Saransk 1-0.
