Sterling gets abuse from Liverpool fans because he left and more specifially because of the way he left the club but you only have to look at the abuse he received at Stamford Bridge and up until the last 12 months, the abuse he received playing for England and being made the scapegoat for poor perforances, to see that it's not just Liverpool fans.
Sterling was never as bad as some made out but long before leaving Liverpool he had numerous issues and built up a bit of a reputation. He was arrested (but found not guilty) of assaulting his ex-girlfriend, there were a few incidients involving that hippy crack and general unprofessional behaviour. There was a running joke at the time that he had about 13 kids by the age of 18. His image changed the day he turned on the press and outed their double standards/casual racism. Ever since then the press have been falling over themselves to prove they're not racist and Sterling's been receiving so much positive press for things that 99% of footballers do.
