Antonio Cassano gives Zlatan a taste of his own teammate kicking medicine

Antonio Cassano returned to Milan's starting XI after suffering a stroke and undergoing heart surgery in November and uncertainty as to whether he would ever play again. And not only did Cassano score the first goal in Milan's 4-1 win over Siena and set up two others, but he also gave Zlatan Ibrahimovic a friendly kick in the backside.

Zlatan, of course, has a well-documented history of kicking his teammates -- including Cassano -- so Cassano's kick not only shows his taste for revenge, but that his bravery is at an all time high. Although, that wicked smirk on Ibra's face doesn't look good for Cassano.
