The Ivory Coast international was coveted by a number of leading European clubs in the summer after he inspired Lille to Champions League qualification on the back of his 22 goals in Ligue 1.
Head of football Raul Sanllehi helped engineer a deal which saw Arsenal beat Napoli to the 24-year-old’s services but Pepe has shown only flashes of his potential during his first six Arsenal appearances.
An injury to Alexandre Lacazette means Pepe is likely to keep his place in the side which entertains Aston Villa on Sunday, looking to bounce back from last week’s capitulation at Watford, and Emery insists he is doing everything possible to illicit an improvement from his star signing.
‘He needs more adaptation,’ Emery said in his pre-match press conference.
‘He is playing good but progressively we know there is going to be more performance in him to help us and I want to do now quickly the last step in the adaptation for us, for example, against Aston Villa.
‘We are working with him first for that adaptation.
‘After the training now we are watching individual videos with him, also to push him to achieve the details tactically we need for him because he is playing well but also we need in our organisation to be strong with every player to improve a lot.’
