João Diogo Alves Rodrigues (born 17 September 1998), known as Kikas, is a Portuguese professional footballer who plays for Estrela da Amadora as a striker.

Kikas was born in Castelo Branco, and finished his youth career with Vitória de Guimarães up north.^[2] He made his senior debut with local club Benfica e Castelo Branco in 2017, scoring 17 goals in his only season as the team finished in third position in the third division, the first outside the promotion play-offs zone. He added four in the Taça de Portugal,^[3] and in January 2018 signed a three-year contract with Belenenses to be made effective on 1 July.^[4]

Kikas' first match in the Primeira Liga took place on 27 August 2018, when he came on as a late substitute in the 1–1 away draw against Moreirense.^[5] Starting on 22 February of the following year, he netted four times in three consecutive league matches, including in a fixture at Benfica that ended 2–2.^[6][7]

On 7 May 2019, Kikas agreed to an extension until 2023 with a buyout clause of €15 million.^[8] Late into the January 2020 transfer window, he was loaned to LigaPro side Vilafranquense until 30 June.^[9]

Kikas continued to be loaned by the renamed B-SAD in the subsequent seasons, to Doxa Katokopias of the Cypriot First Division,^[10] Mafra in the Portuguese second tier, União de Leiria in the third,^[11] and Estrela da Amadora in the second. Having helped the latter to return to the top flight in 2023 after a lengthy absence, that summer he joined them on a free transfer and a two-year deal.^[12]

On the final matchday of the 2023–24 campaign, Kikas scored the only goal of a 1–0 win over Gil Vicente to secure Estrela's survival in the main tier.^[13]
