Idrissa Gana Gueye helped Senegal defeat Tunisia to reach the Africa Cup of Nations final for only the second time in their history.

The Everton midfielder played the full 120 minutes of a contest that went to extra time and was at the centre of a key moment when a late penalty award against Senegal was overturned by VAR.

With Senegal leading through Tunisia defender Dylan Bronn's 100th-minute own goal, a spot-kick was initially signalled by the referee after Salif Sane's headed clearance glanced off Gana's elbow.

However, replays showed the Blues star was clearly trying to move his arm away from the ball, prompting the referee to change his ruling.

Both sides had earlier had penalties saved in normal time.

Senegal, who will be without captain Kalidou Koulibaly due to suspension, will now take on Algeria in Friday's final hoping to lift their first Afcon trophy.

Algeria beat Nigeria 2-1 to book their place, with Manchester City's Riyad Mahrez netting a stunning 95th-minute winner.
