Let's do the order of events...
Costa kicks up a fuss and the media are all over the fact he wants a big money move to China
Following this, Costa's form dips and goals dry up
The fans continue their top class support for him and the team
He starts firing again and doing his job
The crowd sing his name again
Season ends and we win the league
Costa gets text from Conte saying he isn't in his plans
Diego keeps talking and says "I'm waiting for Chelsea"
This guy has been brilliant for us, that isn't even in question, but when you decide mid season, not just mid season but a season you are absolutely flying, not just yourself but the team you have to question why the fuck he decided to make noises. Stay the fuck quiet, stay focused because at the end of this rainbow might just be one of the biggest medals and CV prints you will ever have. OK so if Conte has sent him a text saying "Your off" maybe it's Conte saying you shot your load here son and I am the boss.
IMO Diego Costa has been great, but he's dropped one fat messy shite in all this, it came in January, now all of a sudden he is trying to play the kidnapped....Nah not for me.
