Algeria's quest to recapture their AFCON title began with frustration in their opening game as a plucky Sierra Leone side held them to a 0-0 draw.
Riyad Mahrez and Co are one of the favourites to lift the trophy once again but they were left stunned by the Leone Stars, who were the better side in the first half and easily could have found themselves a couple of goals ahead with better finishing.
Alhaji Kamara and Kei Kamara were both guilty of some agonising missed chances to take a shock lead, while Mohamed Turay also went close.
