Wales are expected to climb to as high as 11th in FIFA world rankings when they are officially released today.
Wales went into Euro 2016 as 26th in the world but are expected to be unveiled as the top-ranked team in Britain.
Two Welsh Labour MPs have added their voices to the calls for Sepp Blatter to stand down as President of FIFA following the arrests in Switzerland as part of an FBI anti-corruption investigation. The Football Association of Wales has said it will vote against Sepp Blatter's re-election as FIFA President.
Rhondda MP Chris Bryant, who's the new Shadow Secretary of State for Culture, Media and Sport, spoke on behalf of the Labour Party when the FIFA arrests were raised at Westminster.
Stephen Doughty MP suggested that Sepp Blatter was not the only FIFA officlal who should quit. He said that after years of allegations about the Zurich based organisation, the Swiss authorities also had some questions to answer.
The Secretary of State, John Whittingdale, said the Swiss authorities were now clearly taking the matter very seriously and working with the FBI. He said a change in leadership at FIFA was badly needed and he was pleased that the UK's four football's associations were all backing UEFA's call for action. He added that "this is merely the latest sorry episode to suggest that FIFA is a deeply flawed and corrupt organisation".
The Football Association of Wales (FAW) says its executives will be voting for Prince Ali bin al-Hussain of Jordan in the Fifa Presidential Elections tomorrow.
It comes amid continued allegations of corruption at the very top of world football.
Wales winger Gareth Bale joins Lionel Messi and Cristiano Ronaldo among the leading contenders for *FIFA's Ballon d'Or award. *The 23-man shortlist for the prestigious world player of the year award was today, with the winner to be unveiled on January 13 in Zurich.
Barcelona forward Messi has won the award for the last four years, with Bale's Madrid team-mate Ronaldo consistently his nearest challenger.
Meanwhile Real Madrid coach Carlo Ancelotti has called for patience as fans wait to see the best of Bale following his record-breaking summer move.
Bale has yet to set the Primera Division alight following his 100million euros transfer from Tottenham and, with the Wales forward battling to return to full fitness, he is also still to complete a whole match for his new club.
He was named in the starting line-up for Saturday's Clasico against Barcelona but was replaced an hour into the 2-1 loss.
"In the last few games he hasn't done extraordinary things, but a player who arrives at a new team, in a new culture, needs time to adapt," said Ancelotti.
"The problem the player has is of adaptation. It's not the same to play in Spain as in England."
Ancelotti also laughed off any suggestion that Bale's price tag had an influence on his decision to start him against Barca.
Gareth Bale posted the new cover of the FIFA 14 game, with him in his new Real Madrid kit, on Twitter.
He admitted it was "great to finally get back to playing" for Wales last night, after an injury lay-off.
The world's most expensive player said he "can't wait" to get to Madrid now, after the international break and ahead of a potential debut on Saturday.
'Hala Madrid' is a popular fans' saying, meaning 'Go Madrid!'
Gareth Bale's world record transfer from Tottenham to Real Madrid has been recognised by an updated cover of the video game FIFA 14.
