Tunisia coach Alain Giresse is growing grey hairs over his goalkeepers, following a pair of errors in their first two games at the 2019 Africa Cup of Nations.
An error by Farouk Ben Mustapha saw Tunisia settle for a 1-1 draw with Angola in their opening Group E match, forcing Giresse to change his keeper against Mali.
However, a blunder from Mouez Hassen led to Mali's opener and it took Wahbi Khazri's deflected free-kick to rescue a share of the spoils.
Ahead of Tuesday's clash with tournament debutants Mauritania, in which the Carthage Eagles need a victory to guarantee their progression to the last 16, Giresse is hopeful his goalkeepers will not let him down.
