Fifa's reputation has never been at a lower ebb, Prime Minister David Cameron has said.
His remarks during Prime Minister's Questions come after the furore surrounding the re-election of Fifa president Sepp Blatter.
Cameron called on world football's governing body to become "more transparent and more accountable.
"I have seen football governance at an international level and I wasn't impressed by what I saw," he said.
Cameron was part of the delegation which travelled to Zurich last year for England's failed 2018 World Cup bid.
Afterwards, he claimed that the world of football governance was "murky" and said he was personally misled by a number of Fifa executives.
Cameron added: "What I would say is this: Fifa's reputation is now at an all-time low and obviously the election with just one candidate was something of a farce but it has to become more transparent and more accountable.
"They have got to prove that they are actually capable of doing the job that they are meant to.
"But ultimately change has got to come from within football and I am sure the Football Association will want to play a very major role in helping to bring that about."
