London Arsenal decided to change its transfer policy, Football London reported.
According to the source, Arsenal face up to some big decisions involving five key players this summer.
Pierre-Emerick Aubameyang, Mesut Ozil, Henrikh Mkhitaryan, Shkodran Mustafi and Sokartis all have deals that expire in 2021, which means they will have two years left on their contracts at the end of this season.
As reported earlier, Aaron Ramsey has already parted with the club. He will be transferred to Juventus in Turin as a free agent.
