Dejan Lovren has demonstrated he intends on taking no prisoners at the World Cup as the Croatian defender continues to limber up for the tournament.

Enjoying a relaxing day by the pool, the Liverpool centre-half decided to challenge his brother Davor to a little one-on-one football.

Being typical male siblings, it wasn't long until it quickly descended into violence.

"I love you brother, but when football is in question I don't care," Lovren barked on Instagram after studding Davor in the gut, hoofing the ball at him and then quite literally kicking him while he was down.

Fraternal love. There's nothing quite like it.
