Queiroz's appointment had long been expected but Colombia had to wait until the end of the recently-concluded AFC Asian Cup UAE 2019 for the Portuguese's contract with Islamic Republic of Iran to run out.

He has signed a four-year contract and his first major task will be to lead Colombia at the June-July Copa America in Brazil.

He said his aim would be to "look after the proud history and the reputation Colombia has today in the world".

Qatar improved to 55th, just missing out on their best ever FIFA World Ranking of 53.

Japan, whose bid for a fifth AFC Asian Cup title was thwarted by Qatar in the final, also saw a surge in their ranking as they improved by 23 spots to 27 to sit behind Iran, who improved by seven to move up to 22.

Qatar's improvement was expected as six of the seven teams they defeated en route to winning the AFC Asian Cup title were recorded against sides who were ranked higher than the Maroons going into UAE 2019.

Qatar, having never advanced beyond the quarter-finals in their previous appearances in the Continental showpiece, were a revelation in UAE 2019 as Felix Sanchez's team recorded seven wins to emerge champions on February 1.

Four of the seven wins were recorded against former AFC Asian Cup winners - Saudi Arabia, Iraq, Korea Republic and Japan - and Xavi said it was just reward for the efforts the Qatar Football Association (QFA) had put in preparing the team.

The Oman Football Association announced Dutchman Verbeek's decision on its social media channels late on Wednesday.

Assistant coach Muhanna Said will be the stand-in coach until a suitable candidate is found, added the Oman FA.

Yuya Osako’s double and a late strike from Genki Haraguchi mean Iran’s AFC Asian Cup-winning drought will extend for another four years after a 3-0 loss at Al Ain’s Hazza bin Zayed Stadium took the four-time winners into Friday’s final at Team Melli’s expense.

Queiroz has been at the helm of the Iran national team for eight years, but he suggested he will no longer continue a reign which has seen him lead the country to back-to-back appearances at the FIFA World Cup.

Appearing in the final four for the first time in 15 years, Team Melli held their own in a competitive first-half, but never recovered from the concession of Yuya Osako's opening goal, with Japan taking full control and ultimately cruising into Friday's final.

It was a forgettable conclusion to an Iranian campaign which had promised so much, but ended, once again, in knockout stage disappointment.

Osako, who was included from the start for the first time since sustaining a hip injury in Japan’s opening game, put the four-time champions in front 11 minutes after the interval before doubling his side’s lead midway through the half from the penalty spot.

The Werder Bremen striker’s double – and Genki Haraguchi’s late third - sent his nation into their fifth AFC Asian Cup final since 1992 and they will face the winners of the semi-final between the United Arab Emirates and Qatar in the decider on Friday.
