release clause is activated.
Brighton & Hove Albion was also interested in transferring him, He scored six goals and assisted three more in the
2017–18 season, which ended in relegation for the
Galician team. The rumoured transfer fee was €6 million, representing the release clause in his contract in case of Deportivo La Coruña's relegation. Andone scored for Brighton in his fourth appearance—and also his first start—away against
Huddersfield Town in a 2–1 comeback victory, and netted again in the next match at the
Falmer Stadium against rivals
Crystal Palace, collecting the ball just inside the Palace half, dribbling into the area and scoring from an acute angle in a 3–1 victory. On 5 January 2019, Andone scored on his
FA Cup debut in a 3–1 away win against
Bournemouth, and a month later he scored in a fourth round replay win against

Southampton, following a rash knee-high challenge on

season-long loan with Turkish
Süper Lig side
