Sarri criticized new signing Daniel Maldini for lacking the attacking instinct of Castellanos, noting he plays too far from goal. He also defended his decision not to play 22-year-old Petar Ratkov, citing language and style barriers.
Conversely, Castellanos has thrived at West Ham, scoring twice and starting every Premier League match. Sarri admits the sale was a financial necessity, but Lazio currently lacks the same sharpness and directness that Castellanos provided.
