Youssef Msakni scored with a long-range shot to hand Covid-hit Tunisia an improbable 1-0 win over 10-man Nigeria in Garoua on Sunday to advance to the Africa Cup of Nations quarter-finals.

Their captain powered home a low shot from outside the penalty area two minutes into the second half to bundle Nigeria out of the tournament.

Nigeria had been the only side to win all three of their games in the group phase and were overwhelming favourites as Tunisia battled without seven players, who were isolating.

But Tunisia, who also had to do without coach Mondher Kebaier because of Covid, advanced to meet Burkina Faso in next Saturday’s quarter-final, also in Garoua.

Burkina Faso held off a gallant rearguard action from 10-man Gabon to advance to the Africa Cup of Nations quarter-finals with a 7-6 victory on penalties after a 1-1 draw in their last-16 tie in Limbe on Sunday.

Ismahila Ouédraogo netted the decisive kick after an incident-packed and energy sapping clash.
