Kivior was interviewed recently and talked about the process of leaving Arsenal.
Chiviol said: "My last conversation with Arteta was when we already knew I was going to Porto on loan. The coach emphasized how great the club is and wished me good luck."
"The earlier conversation, when I made my request for a loan, was a little more difficult. I had never done this before, but I felt it was time to talk to him face to face. He understood me and supported my decision."
