Born in Paris, Nteka left his hometown and joined Spanish side Betis San Isidro on a trial period in January 2017, after having been called by an agent proposing a move to Madrid and trials with bigger clubs.[2][3][4] He made his debut for the club during the 2016–17 season, scoring three goals in 13 appearances. While at Betis San Isidro, Nteka was left without a paycheck. Eventually, the club offered him 300 euros a month, and to justify the expense, had him take care of the training ground and clean the dressing room.[5]
Fuenlabrada
In November 2017, after a failed move to Rayo Vallecano B,[6] Nteka joined Fuenlabrada and was initially assigned to the reserves in the regional leagues.[7] However, he never played for the B-team, being immediately included in Antonio Calderón's main squad and making his first-team debut on 7 January 2018, starting and scoring the opener in a 2–1 away defeat of Deportivo Fabril in the Segunda División B.[8]
Nteka renewed with Fuenla on 22 June 2018, after agreeing to a three-year deal.[9] He was a regular starter during the campaign, contributing with eight goals as his side achieved promotion to Segunda División for the first time ever.[citation needed]
Nteka made his professional debut on 17 August 2019, starting in a 2–0 away defeat of Elche CF.[10] He scored his first professional goal on 13 October, netting his team's only in a 2–1 away loss against Mirandés.[citation needed]
Nteka scored eight goals for Fuenla during the 2020–21 campaign, being the club's top goalscorer as they achieved a mid-table finish.[citation needed]
Rayo Vallecano
On 28 July 2021, Nteka signed a five-year contract with Rayo Vallecano, newly promoted to La Liga, along with teammate Pathé Ciss.[11] He made his top tier debut on 15 August, starting in a 3–0 loss at Sevilla.
On 29 August 2021, Nteka scored his first goal for Rayo against Granada in a 4–0 home victory.[12]
Loan to Elche
On 1 February 2023, Rayo announced the loan of Nteka to fellow top tier side Elche until the end of the season.[13]
