Probably the best way of looking at this case.....Jason Roberts of Blackburn Rovers...

" Suarez and Liverpool claimed "negro" was a commonly used term in the striker's homeland of Uruguay and that it was often used affectionately there.

But Roberts, who received an MBE in 2010 for his services to sport in Grenada, added: "To use those words in that tone and context is certainly not acceptable in our leagues.

"It's not good enough to say, 'It's OK where I come from, so we do it here'. That's not the way we judge our society or the Premier League.
