Algeria captain Riyad Mahrez has expressed confidence that his side’s Africa Cup of Nations quarterfinal clash against Nigeria will present a very different challenge from their narrow round-of-16 victory over the Democratic Republic of Congo.

The Desert Warriors booked their place in the last eight with a hard-fought 1–0 win over DR Congo and will now face the Super Eagles in what promises to be one of the most exciting fixtures of the tournament. Nigeria and Algeria are the only two teams to have won all their matches so far in Morocco, each recording four consecutive victories.

While Nigeria arrive with the tournament’s most potent attack, having scored 12 goals, Algeria boast the best defensive record, conceding just once. The contrast in styles has already set the tone for a tactical battle that fans are eagerly anticipating.

Speaking ahead of the match, Mahrez highlighted the difference in approach between Nigeria and DR Congo, suggesting that the Super Eagles’ style could open up the game. “In our next game, we’ll be up against a different team than DR Congo,” the former Manchester City and Leicester City star told reporters. “We think the next game will be more open, giving us more room to show what we can do, and we need to be ready for it.”

The highly anticipated encounter will take place at the Marrakesh Stadium on Saturday, with the winner set to face either Morocco or Cameroon in the semifinals.

Opinion: This quarterfinal feels like a classic AFCON showdown — Nigeria’s firepower against Algeria’s defensive discipline. Mahrez’s expectation of a more open game could play into the Super Eagles’ hands, especially given their attacking confidence and momentum. However, Algeria’s ability to stay compact and absorb pressure may test Nigeria’s patience and tactical maturity.

Ultimately, this match could be decided by fine margins: a moment of brilliance, a defensive lapse, or a tactical tweak from the touchline. For fans, it’s the kind of game that defines tournaments — two unbeaten giants, contrasting philosophies, and a semifinal place on the line. Whichever team adapts best to the moment will take a big step closer to continental glory.
