So it turns out Diego Costa is just as bonkers off the pitch as he is on it.
Chelsea have released their latest 'Unseen' episode on their YouTube channel which features the Blues in training ahead of Saturday's trip to Bournemouth, and there are some interesting scenes featuring the striker.
First up, he decides to hijack a mini tractor of sorts before driving over practice cones, then proceeds to smash up hurdles in a faux rage, much to the dismay of the training ground staff.
What is wrong with that man!?
