The Gunners boss has hit out at the Spanish giants,
suggesting their approach to buying and selling players is not
sustainable unless a club has "hyper unlimited revenue"
Mesut Ozil, who joined the Gunners during the summer transfer window in 2013, left Madrid as Gareth Bale was signed, while Angel Di Maria joined Manchester United in 2014 following the arrival of James Rodriguez and Toni Kroos.
Such an approach is at odds with Wenger's philosophy - the Gunners boss signed only Petr Cech ahead of the 2015-16 season - and the Frenchman believes buying and selling players every summer does not lead to consistent success.
