A total of 64 athletes from 28 countries are set to compete in the four male and four female Olympic divisions in the season closing event, taking place in Mexico for the second successive year following last December's finals in Querétaro.

A top-six finish in the Grand Prix rankings - which also account for performances in Grand Prix legs in Moscow, Samsun and Manchester - will be enough to guarantee qualification for next year's Olympics in Rio de Janeiro.

Tomorrow's most eagerly awaited duel will come in the men's under 80kg division, which has produced thrills and spills throughout a pulsating season.

In the absence of injured world champion Mehdi Khodabakhshi, Iran's challenge will be led by the under 74kg world gold medallist Masoud Hajizavareh.

He will be up up against the likes of Russia's Albert Gaun, Moldova's world number one Aaron Cook and a British duo in Olympic bronze medallist Lutalo Muhammad and world silver medallist Damon Sansum. 

Another Iranian in Falleh Ashourzadeh is expected the lead the way in the men's under 58kg event, with competition to come from South Korea's second ranked Kim Tae-hun.

All eyes will be on China's world champion Wu Jingyu in the under 49kg competition although she enters the event second ranked due to have missed several stages, with Croatia's Lucija Zanonovic the top seed.

Haby Niare of France leads the way in the under 67 division, with Taiwan's world champion Chuang Chia Chia and Nur Tatar of Turkey among her likely opponents.

On Sunday (December 6), the men's under 68kg is the most appetising of the four events.

Russian's Samsun Grand Prix winner Alexey Denisenko leads the ranking lists but will face tough competition from two world champions, Turkey's flamboyant London 2012 Olympic gold medallist Servet Tazegul and Belgium's Jaouad Achab, stepping up from the non-Olympic under 63kg category.

The form man, however, is South Korea's second-ranked Dae Hoon Lee, a former double world champion who dazzled en route to victory in Manchester in October.

Another star in the British city was Britain's Jade Jones.

The top-ranked Olympic champion, nicknamed the "headhunter", will be looking to continue that form against arch-nemisis Eva Calvo Gómez of Spain.

It could be a good day for the British team, who have been sleeping in altitude tents to adjust to the conditions here, with world champion Bianca Walkden also due to be in action in the heavyweight over 67kg category.

She will face stern competition from top-seeded Serbian Milica Mandic, as well as from France's Gwladys Epangue and China's under 73kg world silver medallist Zheng Shuyin, who beat Walkden in the final in Manchester.

A home challenge could also come from Mexico's Maria Espinoza.

In the men's heavyweight division, meanwhile, the top two ranked fighters are each from Uzbekistan, with world champion Dmitry Shokin and Jasur Baykuziyev each looking to lay down a marker in a battle for the one available place at Rio 2016. 

In a wide-open field, other contenders could include the likes of Radik Isaev of Azerbaijan and Anthony Obame of Gabon.

“The Grand Prix Final is always one of the most exciting competitions of the year,” said WTF President Chungwon Choue.

"With the added incentive of Rio 2016 qualification, I am sure this year’s final will be even more special.”

A WTF Executive Board meeting will then take place on December 7 followed by the annual WTF Gala Awards Ceremony.

A player, coach and referee of the year will all be named, as well as an inaugural "Kick of the Year" recipient.

On Tuesday, (December 8), the two-day World Cup Taekwondo Team Championships is set to then begin, with eight male and seven female teams, comprising 89 athletes, set to participate in an innovative tag-team format, creating, what WTF officials claim, will be a "fast-and-furious spectacle".

All action will take place at the Sala de Armas - the Olympic fencing venue in the Magdalena Mixihuca sports complex - after being moved from the initial Gimnasio Olímpico Juan de la Barrera location due to concerns over the impact of substantial road works and rennovations taking place there.
