Chelsea boss Jose Mourinho is weighing up Diego Costa's future this week.
The Daily Star says Costa was angry at being axed for the London derby at Tottenham and made his disgust clear to the rest of the world.
The hot-headed striker tossed his bib towards Mourinho in stoppage-time after being left on the bench at White Hate Lane.
His latest show of dissent came after he rowed with Mourinho during Wednesday's 4-0 Champions League win at Maccabi Tel Aviv.
Costa is now likely to find himself out in the cold with huge question marks over his long-term future.
