Onyinye Wilfred Ndidi is a Nigerian professional footballer who plays as a defensive midfielder for Süper Lig club Beşiktaş and the Nigeria national team. Ndidi was part of the Nigerian youth setup during his time at Nathaniel Boys of Lagos. While playing the African U-17 Championship with Nigeria, he was excluded along with two other players from the competition as a precaution, following an MRI age test that suggested he was just slightly above the threshold. Notwithstanding, he joined up with his teammates in the U-20 team the following year, forming the bedrock of the midfield. He was called up to the senior Nigeria national football team on 8 October 2015, making his debut in the friendly game against DR Congo, and playing again a few days later in the 3–0 win against Cameroon, when he replaced John Obi Mikel in the 63rd minute. He was selected by Nigeria for their 35-man provisional squad for the 2016 Summer Olympics. In May 2018 he was named in Nigeria’s preliminary 30-man squad for the 2018 World Cup in Russia. He was included in the African Cup of Nations 2019 squad and played in Nigeria's first match against Burundi. On 25 December 2021, Ndidi was selected in Nigeria's 2021 Africa Cup of Nations 28-man squad by Nigeria's caretaker coach Austin Eguavoen. On January 22, 2022, after the Africa Cup of Nations, Cameroon 2021 Group Stage, Confédération Africaine de Football (CAF) shortlisted Ndidi in the group stage's best team as a substitute alongside Mohamed Salah and Sadio Mane. Ndidi grew up in the barracks as his father was a serving Army officer before his retirement. Discipline and education were the priority there, while football was a passion his father frowned upon. “Any time my dad went to work I would go and play,” Ndidi said in an interview with BBC World Service. In May 2019, Ndidi married his longtime girlfriend Dinma Fortune in Abuja. In 2019, Ndidi started studying for a degree in Business and Management at De Montfort University.
