According to the Daily Telegraph, Arsenal has asked Sane about the conditions for joining, while the German winger is evaluating multiple options.
Sane is 29 years old and his contract with Bayern will expire next month. If he fails to reach a contract extension with the Bundesliga giants, he will become a free agent after entering July.
Arsenal coach Arteta worked with Sane at Manchester City. At that time, the former was a member of Guardiola's coaching team, and the latter was an important member of Manchester City's lineup. During his time at Manchester City, Sane helped the team win two Premier League titles. This could free up a winger position as Sterling will return to Chelsea after the loan period ends.
