Qatar vs Algeria Prediction
This will arguably be the toughest game of the competition thus far, with the high-flying hosts taking on the reigning AFCON winners.
Given the quality of attacking options in both their squads, expect plenty of goal-mouth action too.
However, we're putting our money on the Desert Foxes to prevail on penalties if there's no separating the sides after extra time.
Prediction: Qatar 2-2 (2-3) Algeria
