World Cup - Six handed reigns at Togo
He will be in charge for Friday's first leg of the first round tie away in Guinea Bissau as well as the return in Lome on Tuesday as Togo bid to advance to the group phase of the African zone qualifiers which start in June.
"He has had talks with the sports minister in Paris and it looks good for him to be the next coach. The federation will make its final decision after the two matches," a spokesman told Reuters.
"It had been planned to sign a deal later but I agreed to bring forward the date of my appointment. If all goes well, then I'll sign to take charge of the rest of the qualifiers," Six told France Football magazine.
Togo were finalists at the 2006 World Cup in Germany but have slipped down the rankings in recent years and are forced to take part in the first stage of Africa's qualifiers for the 2014 finals in Brazil.
The 57-year-old Six, who has had a limited coaching career, was part of France's winning team at the 1984 European Championship and had a club career that included spells at Aston Villa, VfB Stuttgart and in Turkey, where he obtained local citizenship and changed his name in order to play for Galatasaray.
