Club career
Midtjylland
Onuachu moved to Danish club FC Midtjylland in 2012 on a scholarship from their affiliate team in Nigeria, Ebedei.[2] He was a prolific scorer for their youth team, and made his first-team debut in the Cup later that year, before making his league debut in December 2012.[2] In June 2013 he signed a new three-year contract with the club,[3] before extending it for a further three-years in August 2015.[4] In early 2015 he was loaned to Vejle BK, before returning to FC Midtjylland ahead of the 2015–16 season.[5]
In August 2019 he signed for then reigning Belgian Pro League champions Genk, who had just appointed Felice Mazzù as coach.[9] At 2.01m tall, Onuachu was seen as being an "atypical" transfer.[10] Onauchu made his debut on 1 September 2019 as a late stoppage-time substitute in a 1–1 draw against Club Brugge,[11] and would score in his next two league games, starting in both a 1–2 defeat against Sporting Charleroi[12] and 3–1 win over Oostende.[13]
Onuachu's second full season at Genk would prove spectacular, finishing top scorer with 33 league goals (35 in all competitions), winning him the Golden Bull for leading Belgian Pro League goalscorer, a feat that saw him named Pro League Player of the Year for 2020–21,[14][15] and 2021 Belgian Golden Shoe winner for the best footballer of the calendar year.[16] Onuachu also won the Ebony Shoe for best African player in Belgium for 2020–21.[17]
The following season saw Genk's league form suffer due to early-season defensive frailty as Cup-winning coach John van den Brom was sacked mid-season and replaced by Bernd Storck. Genk reached the European play-offs, finishing behind Gent in the table, finishing sixth overall. Onuachu was third-highest scorer in the league for 2021–22 with 21 goals, behind Deniz Undav of Union St-Gilloise on 26 and Michael Frey of Royal Antwerp on 24.[21]
In scoring four goals against Sporting Charleroi on 4 November 2022, Onuachu became the first Genk player to achieve this feat since Sonck, in 2003.[22][23] Onuachu scored 16 league goals for Genk up to the end of January 2023, with Racing ten points clear of Union St-Gilloise at the top of the Belgian Pro League. After expressing frustration previously at being unable to secure a move to one of the five richest European leagues, Onuachu said at the start of January 2023 he was determined to help Genk stay top and win the title.[24] Onuachu scored twice in his final game for Genk, a 4–0 win over bottom club Seraing, to once more propel him to top spot in the Pro League scoring charts, as finally a major bid was made for the Nigerian striker from a club in a major league.[25]
Southampton
On 1 February 2023, Onuachu swapped title-chasing Genk for relegation-threatened Premier League club Southampton on a three-and-a-half-year contract.[26][27] On 4 February 2023, Onuachu made his first Premier League appearance for Southampton in a 3–0 defeat against Brentford, replacing Mohamed Elyounoussi at half-time.[28]
On 11 September 2023, Onuachu joined Trabzonspor on a season-long loan.[29][30] He scored on his debut for the club on 17 September 2023 in a 3–0 victory against Beşiktaş.[31]
On 26 March 2019, Onuachu scored his first goal for Nigeria in a friendly match against Egypt. The goal was scored within the first ten seconds of the game, and the fastest ever scored for Nigeria.[34] Following the goal Onuachu was heralded as the "toast of Nigerian football", with "his coach, team-mates, journalists and fans talking about him".[35] He was selected to the Nigeria squad for the 2019 Africa Cup of Nations.[36] He played in Nigeria's 1–0 win over Burundi,[37] as the Super Eagles reached the semi-finals, losing 2–1 to Algeria in the last four,[38] then beating Tunisia 1–0 in the bronze-medal match.
