West Ham United has expressed interest in acquiring Lazio's striker Valentin Castellanos during the upcoming summer transfer window. The Argentine, 26, has impressed in Italy with 22 goal contributions this season. The English club sees him as a potential replacement for German striker Niclas Fullkrug, whose performance has been hindered by ongoing injury issues. The prospect of playing in the Premier League is likely to be appealing for Castellanos, and West Ham is reportedly prepared to make a substantial offer to tempt Lazio. Previously, Castellanos had been linked to West Ham, indicating the club's persistent interest in him. As Castellanos approaches the peak of his career, his technical skills are believed to be well-suited for the Premier League, and he could become a crucial player for West Ham, which might also enhance his chances in the national team. West Ham's need for a consistent goal-scorer is clear, given their struggles in the absence of a reliable striker, making this transfer a top priority for manager Graham Potter in the forthcoming transfer window.
