The Chilean has been widely linked with a move away from the Emirates Stadium, but his manager expects him back at the club soon
Alexis Sanchez has been told by Arsene Wenger to respect his Arsenal contract, with the forward's return to the club to be delayed by illness.
Sanchez was due to report for pre-season training on Sunday, having been given extended leave following international duty for Chile at the Confederations Cup.
With Sanchez entering the last year of his contract at the Emirates Stadium, clubs including Bayern Munich, Paris Saint-Germain and Manchester City have been linked with a move for the 28-year-old.
