Arsenal boss Mikel Arteta says he's a fan of new Manchester United manager Ralf Rangnick.

Arteta has described United's appointment of Rangnick as "really interesting" ahead of the two sides facing off on Thursday.

"He's been one of the top coaches," Arteta said.

"He's made some radical changes in some areas and is a really interesting person in the football world and a really interesting appointment for the football club."

Rangnick won't be in charge tomorrow with his work permit not yet secured.
