DO NOT INSULT THIS MAN'S FAMILY!!!
German soccer player Toni Leistner was so furious with a trash-taking fan after a loss Monday, he climbed into the stands and manhandled the dude ... and it's all on video.
Leistner and his Hamburg squad had just lost to Dynamo Dresden in 4-1 shellacking in the German Cup when he heard someone spewing insults from the crowd.
The 30-year-old stopped a live TV interview and jumped into the stands, walked right up to the man he believed to be the trash-talker ... grabbed the dude by the shirt with both hands, and shoved him to the ground.
