WATCH : Diego Costa parties in an Atletico shirt and insults Conte

Diego Costa has always been someone that has played on the edge, sometimes even crossing the line on the field.

He is a terrible opponent to have, but a wonderful person to have on your side. His team mates always praise him while his rivals cannot stand the sight of him.

But it looks like this time he has gone a step too far!

In spite of playing a crucial role in Chelsea’s last two Premier league triumphs, Costa has constantly been flirting with the idea of returning to Spain.

He first made his name with Atletico Madrid, when he scores a bucket full of goals en route to their historic La liga triumph. Costa is fondly remembered in Madrid, as the fans remember his role in the club’s recent history.

Costa’s future was put in doubt when Tianjin Quanjian bid 70 million for him in the January transfer window. That turned his head, as the striker seriously considered moving to China.

Conte changed his mind then, but was still looking at getting another striker in the summer transfer window.

Reportedly, Conte texted Costa after the season ended and told him to look for a new club. Unsurprisingly, Costa was unimpressed.

In the above video we can see Costa partying in Brazil, wearing his old club’s shirt. You can also seem him insulting Conte, clearly unaware of the camera recording his every action. Or maybe he did?

Well you never know with Costa do you? But Chelsea fans must be wondering if Costa has effectively ended his time at Stamford Bridge.
