On 16 January 2021, Primera Iberdrola club Real Betis Féminas signed Amorós to a contract until 30 June 2021, with an option to extend by one year.[9] However, Amorós and the club mutually ended the contract in May 2022 following a 9th-place finish in the 2021-22 season.[10]
Following the suspension of head coach and general manager James Clarkson, the Houston Dash appointed assistant coach Sarah Lowdon as acting head coach. On 15 June 2022, the Dash appointed Amorós as the club's new interim head coach pending visa approval.[11] Amorós would not join the team until 12 July while waiting for his visa.[12][13] In his first match managing the Dash on 16 July, with newly acquired striker Ebony Salmon scoring a hat-trick, the Dash defeated the Chicago Red Stars 4–1.[14]
