Arsenal director of high performance Darren Burgess is set to leave the Emirates after two years with the club.
It is understood Burgess, 45, was sacked days after the Gunners' 4-1 Europa League final defeat by Chelsea.
Head of performance Shad Forsythe - who had been close to joining AC Milan - will now remain at Arsenal and be elevated to a more senior role.
Former chief executive Ivan Gazidis left his role at the club to join Italian side AC Milan in September.
