€29m Deal Confirmed; Hammers Also Land Pablo in Double Striker Swoop.

Taty Castellanos

West Ham United have kicked off the January window with a bang, securing Valentín ‘Taty’ Castellanos from Lazio for €29m, confirmation on January 1, 2026.

The 27-year-old Argentine international has agreed a long-term contract at the London Stadium, marking a significant statement signing for Nuno Espírito Santo’s side battling relegation threats.

Castellanos – known for his physical presence, hold-up play, and clinical finishing (famous rabona assists included) – struggled for consistency at Lazio this season (limited goals amid injuries) but brings proven quality from spells at NYCFC (MLS Golden Boot) and Girona.

This follows the earlier agreement for Pablo Felipe from Gil Vicente (€20-23m), giving West Ham two new strikers upfront in a bold double swoop. Outgoings like Niclas Füllkrug (loan to AC Milan) and Luis Guilherme (to Sporting) facilitate the arrivals.

Medical and official announcements imminent.
