Everton contract rebel Kevin Mirallas has sensationally gone awol from Everton's training ground after a huge bust up with blue boss Roberto Martinez. The Belgian confronted the Catalan manager by jumping at him from a finch farm window and demanded that the team change their tiki taka style in favour of quick direct forward passing and bombarding the ball in and around Mirallas and his fellow want away international team mate Romelu Lukaku.
Martinez is said to have refused to listen to Mirallas as he had approached him from a height instead of at ground level, thus going against Martinez' philosophy of keeping it on the ground.
The Belgian is no stranger to controversy,having snatched the ball of regular penalty taker Leighton Baines against West Brom before missing from 12 yards. He then refused to emerge for the second half, as his team mates refused to call him King Kev, instead Mirallas immediately left Goodison and took a shit on the Dixie Dean statue on his way out
