But Monreal believes Mikel Arteta would be a great coach to play under.
The Real Sociedad defender told the Guardian: “(Arsene) Wenger's departure was controversial. There was a big divide among the fans, we saw it every game.
“After 22 years, the first post-Wenger coach was always going to have a difficult role. Maybe Unai didn't get the time he needed but he did a good job.
“I would have loved to have played under Arteta. I spoke to Hector about that. I had him as a teammate and I would have loved to see him as a coach; there's that curiosity in me.
“But I chose another path and came to San Sebastián. I'm happy for me and him because things are going well."
