The abuse first started with many in Liverpool, not a minority, because Sterling wanted to move to better himself as a footballer, win trophies and earn more money (he has achieved all 3). The usual stuff followed from them - death threats, on-line vitriol etc. which has been a feature of the behaviour of elements of their fan base many times. It then grew from their media 'personalities' who hounded him in the press and on TV. " Nobody leaves Liverpool", I recall Phil Thompson saying. He was far from alone and, with many other ex Liverpool players, in effect, backed a campaign of hatred against Sterling (though they will deny it but it was clear for all to see). This was picked up and developed by the wider media over time, not least The Sun, which fed the jealous and racists in our society, as well as the usual extremes in opposition fans. Now it is big news but this has been happening for a long time.
The media are now under the spotlight and some do not like it. Custis in The Sun, who never fails to back Mourinho come what may, immediately resorted to self justification. Brazil on Talk Sport this morning is another who needs educating. They are both dinosaurs and typical of many. Fortunately, others as evidenced by Sunday Supplement yesterday, recognise the role of the media and the need to consider very carefully their actions and part in this.
