John Terry and Gary Cahill wrestled each other

Sad one, Chelsea defenders skipper John Terry and Gary Cahill both wrestled each other whilst defending a Chelsea corner leaving opponent free to fist on their goal post.
           
Wonders shall never end, this is strange could they be fighting for who is going to score an own goal or what? this is just so funny.. Lols
           
This above picture show's how free and unmarked opponent behind both defenders wrestling each other for the ball.
