Diego Costa has launched a stinging attack on Chelsea boss José Mourinho after the Spanish striker was dropped for the Pensioner’s London derby away to Tottenham Hotspur.

The 27-year-old, who has found himself out of form and now out of favour within Stamford Bridge, was an unused substitute in Chelsea’s 0-0 draw against their North London rivals, prompting a wave of anger, frustration, and internal angst after the final whistle.

Costa, who threw his substitute’s bib at his manager towards the end of the match, told reporters: ‘It’s just so unfair. What’s Eden Hazard got that I haven’t? God, I wish I was never born. Maybe if I ran away, José would notice me. Or if I cut myself. No one knows what it’s like to be me’.

Mourinho reacted to Costa’s tantrum by telling reporters: ‘It is unfortunate that he is choosing to act out in this manner. But my new medical staff tells me it’s just a phase that he’s going through, and that he’ll come out of it eventually’.

Costa was unavailable for further comment, preferring instead to get pissed on shop’s own brand lager down the local park with his mates.
