Arsenal boss Mikel Arteta has explained signing Oleks Zinchenko.

Arteta was speaking after their 6-0 preseason win against Sevilla.

He said, "First of all, his mentality. He's used to winning - winning is the only thing and winning in the right way.

"He's a perfectionist and a really demanding boy, I know him so well, and after that he brings qualities that we didn't have in the squad.

"He gives us a different option to play within the role in different spaces, and I'm really happy to have him."
