Researchers found that visitors to St James's Park and Stamford Bridge grounds are most likely to hear a torrent of obscene language and chanting.

The researchers attended matches at every Premiership venue and ranked each one according to the amount of bad language they heard during a game and the level of swear words used.

Charlton Athletic fans scored the worst - or the best depending how prudish you are. They fell to the bottom of the Sunday Mirror's "league of shame" by a comfortable margin, with less than half the swearing found at Newcastle.

A Newcastle United spokesman said the club was taking action to combat the use of offensive language.

"We have received complaints from fans about obscene and racist language. Anyone heard using it will have their season tickets taken off them," he said.
