The unflinching loyalty Issa demonstrated towards his country earlier this season ultimately cost him his first-team place at Watford.
His decision to travel to the African Nations Cup rather than help the Hornets' failed push for the play-offs saw him fall out with club manager Gianluca Vialli.
Frozen out of the team and slapped on the transfer list, Issa must hope his lack of match practice does not show at the World Cup.
In his favour, the former Dunkerque and Marseille player is one of his country's most experienced and consistent performers.
He has almost 40 caps to his name and has also captained the side on several occasions in the past.
