Arsenal winger Willian has no doubts about the managerial quality of Mikel Arteta.

The Brazilian joined the club from Chelsea in the summer and has been wowed by Arteta's tactical acumen.

The Spaniard is coming in for some criticism after the Gunners have made an indifferent start to the Premier League.

Willian believes Arteta will find the formula for consistent success with the team sooner or later.

"He'll be a top manager, I've no doubt about it," Willian told FourFourTwo.

"The potential is there, as is the ambition.

"In a few years he'll be considered one of the best managers in the Premier League – and the world.

"Obviously you must win trophies to be considered one of the best, and it will happen for him sooner rather than later."
