As the qualifiers for the 2021 Africa Cup of Nations reconvene this week, Nigeria gear up for the doubleheader against Sierra Leone, starting with the home leg at the Samuel Ogbemudia Stadium in Benin City.The Super Eagles are currently at the top of Group L after winning both group games last year. They saw off Benin in a 2-1 comeback victory before thrashing Lesotho 4-2 on the road.Sierra Leone, meanwhile, are looking to qualify for the tournament finals for the first time since 1996 under returning manager John Kiester, who's confident ahead of his second spell with the side.His two-year reign in charge of the Leone Stars ended last year after he stepped down following a poor start to the qualifying campaign, which saw them draw to Benin and lose to Lesotho.However, the England-born former midfielder was rehired in August this year and has urged the nation "to be positive" ahead of this week's make-or-break doubleheader as he embarks on a "rebuilding process".Nigeria vs Sierra Leone Head-To-HeadThe West African nations have met 14 times previously, with Nigeria the dominant force having claimed nine wins compared to Sierra Leone's meager two.The upcoming clash will also mark their first since February 2011, when Nigeria narrowly beat Sierra Leone in a 2-1 friendly international.#Afcon2022q November fixtures for 🇳🇬🦅 #SoarSuperEagles #Team9jaStrong pic.twitter.com/lbtTJmIaTI— 🇳🇬 Super Eagles (@NGSuperEagles) October 30, 2020Nigeria Form Guide (all competitions): D-W-W-L-DSierra Leone Form Guide (all competitions): L-D-LNigeria vs Sierra Leone Team NewsNigeria have recalled Napoli striker Victor Osimhen and Rangers FC star Joe Aribo, both of whom missed last month's friendlies against Algeria and Tunisia.
