"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.

The 57-year-old Six, who has had a limited coaching career, was part of France's winning team at the 1984 European Championships 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.
