"It goes without saying," he said.

"The one thing that is the strength of the club is we have a tight-knit group who are best mates on and off the pitch.

"This has hit our club very hard because of that."

Mitrovic spent the last three seasons with the Vikings playing in the Football Victoria men's state league three competition. He also played in Ballarat City's academy program and spent time with the Forest Rangers in the Ballarat District Soccer Association.

Known for his attacking style of play, Smith said he was passionate, feisty and skillful with the ball.

"He just loved playing. That was his outlet, to go out and express himself on the weekend," he said.
