Overview
- Tzolis was pulled off after about 16–18 minutes of Greece's Nations League draw with the Netherlands on Thursday after grabbing his hamstring and receiving on-pitch treatment.
- Greece coach Ivan Jovanović said the decision to replace Tzolis was made with medical staff to protect the player and because they suspected a muscular issue.
- Multiple outlets report Tzolis will return to Arsenal for scans and a formal assessment, with the club awaiting results to judge how long he might be sidelined.
- The knock compounds an already stretched Arsenal squad during the international window, which has seen Kai Havertz also assessed for a hamstring problem and William Saliba ruled out until November.
- If Tzolis is unavailable, Mikel Arteta may need to shift Eberechi Eze or use other wide options for the home match against Leeds United on October 10 while monitoring scan results closely.
