On July 23, 2026, Arsenal officially announced the signing of Greek international winger Christos Tzolis from Club Brugge. The 24-year-old player completed his medical examinations on July 22 and has signed a five-year contract with the London-based club. The deal is valued at 40 million euros, making it the most expensive transfer for a Greek footballer in history.

This move surpasses previous high-profile transfers, including Kostas Manolas’ move to Napoli in 2019 for 36 million euros and Charalampos Kostoulas’ transfer to Brighton. Tzolis earned this opportunity following an impressive season where he recorded 22 goals and 29 assists in 52 appearances. Following the official announcement, the player is set to join the Arsenal squad immediately to participate in the team's upcoming pre-season training under manager Mikel Arteta.
