According to Calciomercato, Leeds United wants to strengthen with Lazio striker Valentin Castellanos in January to make it easier to secure their stay. Castellanos, who has been described as sensational, has been on Leeds' wish list for years, but a transfer to Elland Road has never happened. Leeds now believes they could convince him to come as early as January, while manager Daniel Farke wants to strengthen the attack for the rest of the season.

Leeds United is among the clubs interested in 27-year-old Argentine forward Valentin Castellanos and has made contact with the Italian club. The forward is considered available for transfer, and Brazilian club Flamengo also remains interested in the player. Recent reports from late 2025 indicate Lazio's asking price is between €30-40 million, while a reported offer of €22.5 million from Flamengo was deemed insufficient.
