FIFA's former head of security Chris Eaton says there's no "credible evidence" of match-fixing in the English domestic game.

But Eaton - a former manager of operations at Interpol who left his post at FIFA in March 2012 and is now director of sport integrity at the International Centre for Sports Security in Qatar - maintains everyone must be guarded to ensure the on-going integrity of what is the world's most watched football competition and biggest gambling market.

Eaton told BBC Radio Five Live's Sportsweek programme: "You hear a lot of allegations, but I have never had any credible evidence about fixing in the English Premier League or the Champions League - that does not mean you should not be vigilant.

"You must be vigilant, this is the most watched league in the world, the most gambled league in the world and therefore the one who has to be the most vigilant."
