"I think he will continue here because he has big priorities here". The 19-year-old, an £8m signing from French side Lorient, was deployed at the base of Emery's midfield, where he was charged with protecting the back four and building attacks from deep.
And now he's looking forward to putting things into practice against Atletico Madrid tonight and Paris St-Germain on Saturday.
"They know that Costa and Koke and all the rest of the players will rejoin us for the season in August, so right now what they're doing is important".
That has created a structure where Gazidis, Sanllehi and Mislintat work together with Emery on most key decisions - a major departure from the Wenger years, when the Frenchman had the final say on almost everything.
In a statement Arsenal said: "We are aware of the speculation surrounding our chief executive Ivan Gazidis".
Recent footage of Perez in pre-season has caused Arsenal fans to urge Emery to give the striker a chance, and he did just that, playing him in the final 30 minutes of the game. "He doesn't really give much away but he's happy".
Smith Rowe was one of three teenagers in the starting line-up as Emery rested his World Cup players - including Mesut Ozil, who has been at the centre of a furore after he quit the German national team claiming racism.
Said the Spaniard: "It was a great goal". "I still have a year left and it is a great feeling to play here".
"Obviously, I came from the academy the same way Emile did, and I'm very happy that our club push these players the way they do".
