Arsenal boss Mikel Arteta has admitted Thomas Partey's fitness is a 'big concern' after reports claimed the midfielder could be out until December.
The Ghanaian missed just seven games in five years at Atletico Madrid but has been plagued with issues since joining Arsenal in 2020 - sitting out 53 fixtures for club and country in that time.
Partey's last appearance for the Gunners came as a substitute in the 1-0 win over Manchester City earlier this month. He suffered a setback in training last week ahead of Arsenal's victory away at Sevilla in the Champions League.
