The Chile global is on an extended break at Arsenal following his participation at the 2017 FIFA Confederation Cup in Russian Federation.
Alexis Sanchez is set to miss his training return at Arsenal this weekend.
Uncertainty has surrounded Sanchez's future this summer, with the Chilean yet to sign an extension to his current contract, which is due to expire next year.
Arsenal manager Arsene Wenger has said many times that he would refuse to sell Sanchez and rather see the former Barcelona man leave on a free transfer when his contract expires.

Negotiations between Emirates officials and Sanchez's advisors have broken down with Arsenal's offer of £275,000-per-week - including a 20 per cent wage rise if and when they re-qualify for the Champions League - failing to sway him.
The 34-year-old endured a dismal first season in the Premier League but recaptured some of his best form at the Confederations Cup, making three penalty saves in the semi-final shoot-out victory over Portugal in Kazan.
