West Ham United said striker Callum Wilson is leaving this week after six years at the club, the side confirmed. Brentford FC now has him on a no-fee transfer deal. Brentford made the move public in a quick release early on Thursday. Wilson spoke immediately after, calling his fresh arrival a team fit with Igor Thiago up front. He added extra firepower to Brentford’s attack right away. No money changed hands for the player himself. Both clubs put out brief notes later in the day. The move finalised the paperwork on time on July 9, 2026.
