"I am very happy with him", he said.
Pressed whether Wilshere's poor injury record was key to him not being able to give him any guarantees, Emery would only say it was a "tactical, technical decision". "The conversation with Wilshere was a very good conversation, very directly together".
"I know this player here is important for the supporters and grew up here in Arsenal, but I couldn't guarantee him a place in the starting 11 and because of that he choose to leave here and I respect this".
But, Emery insisted his squad needs to be bursting at the seams with players willing to step up.
"I want to work with Petr Cech, with Bernd Leno, with Emiliano Martinez, with Matt Macey, with Ospina", he told reporters (via the club's official website). "I said to Ivan, Raul and Sven [Gazidis, Sanllehi and Mislintat, the collective dealing with contracts and transfers] he's an important player for me".
Emery has been busy putting his stamp on Arsenal's squad for his debut campaign, with five players joining the club during the close-season.
'I want all the players showing their best quality on the pitch in each training session and each match'.
France youth global Guendouzi is Emery's fifth signing and follows Switzerland full back Stephan Lichtsteiner, Greece defender Sokratis Papastathopoulos, German keeper Bernd Leno and Uruguay midfielder Lucas Torreira.
Guendouzi, a France U20 global, said that Arsenal is his dream club, one that he wanted to play for since childhood. But will be open to new signings in case "a big opportunity" presents itself.
The first two weeks for us is to start knowing the club, knowing the players, knowing all the people who are working with us. We will only sign a player in the next month if he's a big opportunity.
