Unai Emery was the man chosen to succeed Wenger as the first new Arsenal manager since 1996, but the club could be looking at another appointment soon with the Spaniard showing little sign of having improved the club's fortunes over the past 17 months.
Emery's first season ended in disappointment. Arsenal blew two chances for a return to the Champions League, winning just one of their last five games to finish fifth in the Premier League and then losing the Europa League final 4-1 to Chelsea.
Often derided by fans for a lack of investment, the club's American owner Stan Kroenke backed Emery with a surprising splurge in the summer transfer market.
Pépé was signed for a club record £72 million fee from Lille, Kieran Tierney and David Luiz brought in to improve a faulty defence and Spanish international midfielder Dani Ceballos loaned from Real Madrid.
