Castellanos is currently under contract with Lazio until 2028, but the club is willing to let him go for around €15 million. This means that other teams can negotiate with Lazio to sign him.

Lazio has already chosen a replacement for Castellanos - Fotis Ioannidis from Panathinaikos. This Greek player has the skills and experience that Lazio is looking for in a new striker.

Castellanos has been impressive this season, scoring 14 goals and making eight assists in 39 competitive matches. His experience playing in La Liga makes him an attractive option for Villarreal and Real Betis.

Before joining Lazio, Castellanos played on loan at Girona in the 2022-2023 season. He scored 14 goals and made one assist in 37 matches, showing his ability to perform well in the Spanish league.
