head of performance Darren Burgess is set to leave the club this summer.
revealed last week that manager Unai Emery had launched an end of season inquest into why the team slumped so drastically at the end of the season.
And Burgess, who arrived at the club in Arsene Wenger

Burgess' departure is still to be finalised but the coach - barring a last-minute change - will leave the Emirates Stadium.
