Villarreal midfielder Santi Cazorla has revealed Unai Emery called him over the summer seeking information about life at Arsenal.

The Spanish midfielder, who was let go by Arsenal in the summer and rejoined former club Villarreal, revealed some of what he told Emery.

"I didn't know him but in the summer [Emery] called me to find out about the team and the club, for a bit more info," he posted to Twitter.

"It's normal to speak to someone who has been inside for their view. I told him what I thought: the things that he had to change and the things he had to reinforce.

"I can't say that [what they were]. That's a secret. But I was clear, direct: I said that it was an incredible club, that had everything it needed to win, but that there were things that had to change. I said it would be hard to change some of them.

"Arsene was there for 23 years and changing 23 years overnight … it needs time. It's an opportunity for [Emery] to take a club like Arsenal and try to make them champions which is what I want and what all Gunners want. I think they have chosen well."
