Maurizio Sarri says he doesn’t actually think there is much to be gleaned from spying on opposition sides, after a week of controversy over Marcelo Bielsa’s approach to last week’s match between Leeds United and Derby County.

The Italian said he is familiar with opposition coaches spying from his time in Italy, but that he has never been interested, and thinks more transparent methods offer superior information.

Asked whether he has ever seen anything like the Bielsa story, Sarri said: “Yes. In Italy, yes. I don't know what to say. I prefer to study my opponents by video.

"I think it's very difficult to have a lot of information in the last two days (before a game). I don't like this. Of course, every coach tries to have information about the opponents. But I don't like the way. It doesn't happen a lot in Italy, but it does happen.”

Sarri then joked about why he has never been guilty of spying.
