Arsenal boss Unai Emery has paid tribute to Sven Mislintat.
The German leaves his job as football operations chief this week.
Emery said, "I have been working with him for eight months and my relationship with him is good. Also, when I arrived here, there were young players coming here, and they decided to because his responsibility is with some players.
"I think he has a very good scouting responsibility for his past and his present. I worked well with him but after, it is one decision between the club and him. I don't know exactly all but I respect him and the club. I worked well with him and I wish good luck for him in his future."
