The Burundi international, who now plays for Eswatini's Malanti Chiefs, has not been considered for the Burundi national team in the last two years due to his heart condition that saw several clubs in South Africa hesitant to take a gamble on him.
Burundi are second in Group C with nine points and Gabon are third with seven points. A draw for the Burundians, who will be playing at home, will see them qualify for Egypt together with group leaders Mali, who are on 11 points.
"Everything goes well this side [in Eswatini], played seven games already, scored two and got a national team call-up," Faty tells KickOff.com.
"The last time [I was selected] was 2016 September."
Asked if he was called up because of his recent performances in Eswatini, he said: "Yes bro, and I'm not sick of that [heart] condition anymore.
"And because it's the last game and we need one point to qualify so they need experienced players and players that have been there before to fight for the nation. That's why the federation and coach called me and asked about my situation. I told them how it is.
"It's a very good feeling and pushes me to work even ore harder. Because here we play two games a week most of the time, this will boost my confidence, but it's already there."
