Former Arsenal director Raul Sanllehi fears that the Gunners have made a 'mistake' by reverting back to how operations were run under Arsene Wenger.
The Spaniard, who first arrived in north London in 2018 following a 14-year spell at Barcelona, was named as the club's new head of football after former CEO Ivan Gazidis departed.
During his time at the Emirates, Sanllehi implemented a new model of directorship in a bid to recover from Unai Emery's ill-fated spell as manager.
Keen to split the running of Arsenal into distinct roles, he pioneered a four-person 'dream team', including head coach Mikel Arteta, technical director Edu, head of football operations Huss Fahmy and academy manager Per Mertesacker.
