His move to Ebedei, located in Sagamu, Ogun State, more than 250 kilometers from Benin City, was the first time he was away from home, and required significant adjustments.

Despite the distance and his prior responsibilities, Onyeka remained committed to pursuing his dreams, something he later recognised as instrumental in developing a resilient mindset.

[6][7] Onyeka distinguished himself again in the next fixture, on 18 February, against the leading Superliga team from FC Copenhagen, where he scored his second league goal for the club at the right winger position as Midtjylland beat the capital side 3–1.

[10] He made his competitive debut for the club on 13 August, the first matchday of the season, starting in a 2–0 victory against Arsenal; the Bees' first ever Premier League win.

[15] Onyeka received his first call-up for the Nigeria national team on 22 September 2020 for the friendly matches against Algeria and Tunisia in Austria on 5 and 9 October 2020, respectively.
