Transfer speculation continues to mount as Valentin Castellanos has been linked in recent days with a move to Real Betis. The forward, currently playing for West Ham, could add a new dimension to the squad if the rumoured interest turns into an official approach before the end of the transfer window. Real Betis are still pushing to finalise terms. However, Sevilla, Flamengo and West Ham are still watching closely and may return with offers of their own. At 1.6 goals scored per game this season, Real Betis already pose a big threat. Valentin Castellanos would be expected to maintain that level and give them another reliable option in attack. West Ham have also been linked with Jaden Dixon while Real Betis are reportedly monitoring Fabian Ruiz and Diego Conde. Need more Real Betis transfer rumours?
