CSKA Moscow went on a boat ride (because that's apparently what you do when you win the Russian Premier League and Russian Cup double) and to entertain themselves on the water, they tried kicking balls at other boats. After one attempt fell short and splashed in the water, defender Sergei Ignashevich launched one that successfully bounced off the window of another boat, eliciting a cheer from his teammates.
You have to enjoy the simple pleasures in life.
