Villarreal midfielder Santi Cazorla admits he's offered Arsenal boss Unai Emery advice on how to "improve the club".

Cazorla says Emery asked for his thoughts on the goings on behind the scenes at the club ahead of his arrival this summer.

"I think it's a club that can improve quite a few things," Cazorla told the BBC.

"I gave him all the information I could to try and help him out during his period of settling in and I think he's very happy and I think he's a great manager for Arsenal.

"But everyone really does have to be patient, when you think you've had the same manager for 23 years, a manager who became a real symbol for the club on a worldwide scale and the fans have to show a little patience with Unai, and the team because there has been a lot of changes.

"I believe that if they do things in the right manner, Arsenal have everything required to be a massive club. I'm sure that in the coming seasons Arsenal will be making that step up in quality which will hopefully enable them to be on a level playing field and able to fight for the title and other big trophies."
