Diego Costa believes that he is targeted by officials and rival players in the Premier League.
The Chelsea striker, who scored the winning goal in Chelsea's 2-1 win over West Ham on Monday, has gained a reputation for being aggressive.
He was booked by referee Anthony Taylor for dissent with just 19 minutes of the match played at Stamford Bridge.
The striker is aware that under new League rules, a referee has the power to book a player if they speak aggressively towards them or complain about decisions.
