Alexander Radulov's passion cannot be questioned after watching this.
The former NHL forward scored the go-ahead - and eventual game-winning - goal for CSKA Moscow against Metallurg Magnitogorsk in Game 1 of the KHL's Gagarin Cup Final on Thursday, and his celebration was ... extremely intense.
Radulov's marker made it 2-1, and his teammates responded with three more goals en route to a 5-1 victory, so they were clearly motivated by his enthusiasm.
Here's the entire sequence, including the goal and the full Radulov reaction. Make sure you watch until the end.
