Algeria will defend an 18-match unbeaten run when the leading African national teams return to action this week after 10 months of inactivity due to the coronavirus pandemic.
The reigning African champions face Nigeria in Austria on 9 October and Mexico in the Netherlands on 13 October ahead of the November resumption of 2021 Cup of Nations qualifying.
Algeria are among 18 of the top 20 ranked countries in the continent who will play one or two international friendly matches, with many being staged in Europe.
The Desert Foxes, who defeated Senegal in Cairo last July to become African champions a second time, last lost in October 2018, away to Benin.
They have won 15 competitive and friendly matches and drawn three since, with the victories including a thrashing of Colombia in France.
Cup of Nations-winning coach Djamel Belmadi has called up 24 stars with Manchester City winger Riyad Mahrez the captain and talisman.
The match against Nigeria is a repeat of a dramatic 2019 Cup of Nations semifinal won by a Mahrez thunderbolt free-kick in stoppage time.
Algeria then edged Senegal 1-0 in the final thanks to an early goal from Qatar-based Baghdad Bounedjah, who is also part of the squad for the friendlies.
Nigeria also play twice, meeting another powerful north African side, Tunisia, in Austria four days after tackling the Algerians.
The game with Tunisia is also a repeat of a 2019 Cup of Nations encounter, with Nigeria winning the third-place playoff 1-0 thanks to an Odion Ighalo goal.
Ighalo, a 31-year-old forward on loan to Manchester United from Shanghai Shenhua until 31 January, was not chosen by German coach Gernot Rohr for this international window.
