The making of Taty Castellanos, the 'X-factor' forward driving West Ham's survival bid

Valentin “Taty” Castellanos has waited four years for the chance now gripping the London Stadium. Since joining West Ham United from Lazio on an undisclosed January fee, the 27-year-old Argentine has struck three times in 11 matches, each goal a header, each moment a jolt of belief for a club still mired in the drop zone yet level on 28 points with Nottingham Forest after Tuesday’s priceless win at Fulham.

His first taste of English football could have arrived in January 2022. Multiple sources tell The Athletic that West Ham’s recruitment staff filed glowing reports after extensive scouting of Castellanos at New York City FC, where he had amassed 42 league goals in 109 MLS appearances. Majority shareholder David Sullivan, however, elected not to sanction any signings that window, and Castellanos’ Premier League dream was deferred.

Instead, he detoured through Girona—where a four-goal demolition of Real Madrid on loan in 2022-23 announced him to European audiences—before a three-season spell at Lazio that yielded 22 league goals in 98 games. When Niclas Füllkrug’s loan to Milan opened a striker vacancy this winter, West Ham finally pounced.

Head coach Nuno Espírito Santo reshaped his attack from 4-2-3-1 to 4-4-2 to accommodate Castellanos and fellow January arrival Pablo Felipe. The tweak has re-energised Crysencio Summerville and captain Jarrod Bowen, who have combined for nine goals and five assists since the turn of the year.

Those who watched Castellanos’ formative years are unsurprised by the seamless adaptation. “The speculation never affected him,” says former NYCFC head coach Nick Cushing. “Training would finish and he’d ask to work on headers, finishing, free kicks—he wanted every tool.” That dedication culminated in the 2021 MLS Golden Boot, presented to him by his mother, Marilu, flown in from Mendoza for the occasion.

Born in Argentina’s wine-country capital and rejected as a youth by River Plate and Lanús, Castellanos began his senior career at 16 with Universidad de Chile. A loan at City Football Group’s Montevideo City Torque became a permanent transfer and, eventually, the springboard to New York. There, compatriot Maximiliano Moralez eased his transition; by 2021, with Heber injured, Castellanos seized the No. 9 role and scored 19 times to share the league scoring crown.

David Lee, NYCFC’s former sporting director, remembers an 18-year-old winger “whose aggression with and without the ball jumped off the screen. We saw a future forward.” The loan to Girona hardened him against elite defenders; the stint in Rome refined tactical nuance. Now, back in England, the late bloomer is compensating for lost time.

All three West Ham goals have arrived via headers: the 120th-minute winner in the FA Cup third-round replay at QPR; the clincher in a 2-0 victory at Burnley; and a consolation in the 5-2 defeat at Liverpool. Each aerial finish traces back to those post-training sessions in Queens, where Castellanos would remain on the pitch perfecting the timing and power that now torment Premier League centre-backs.

“He generates incredible force on headers,” Cushing says. “My favourite memory is the 109th-minute winner against New England in the 2021 play-offs—he just destroyed the defender.” West Ham hope for similar moments between now and May. Nuno, speaking ahead of Monday’s FA Cup fifth-round tie with Brentford, praised the striker’s instant adaptation: “Taty’s brought energy; we expect much more.”

Level on points with safety, West Ham believe they have located the elusive X-factor. After four years of circling, Taty Castellanos has finally landed in east London, and the survival fight now carries an unmistakable Argentine accent.
