Andrei Arshavin put in a vintage performance for Zenit St. Petersburg on Saturday. Coming on as a 54th-minute substitute against CSKA Moscow, Arshavin helped set up teammate Vladimir Bystrov for the match's first goal in the 63rd minute.

Bystrov threw himself into the goalpost to score with a header and after celebrating a bit, he realized he was hurt (hamstring?). He then laid down, clearly in some pain, as his teammates surrounded him to celebrate. And that's when Arshavin decided to stand on Bystrov's stomach for a second.

Arshavin was likely just goofing around, telling his friend to get up in his own way, and didn't realize Bystrov was really hurt. But as we know from Andrei's glorious Q&A sessions, trying to decipher what he's thinking can be a mind-bending proposition.

Bystrov then came out of the match (still holding the back of his leg) and Arshavin went on to score his first goal for Zenit since rejoining the club on loan from Arsenal.
