Premier League clubs are following Napoli sensation Lorenzo Insigne.

Insigne has been tipped for big things by Pescara coach Zdenek Zeman, where he is currently on-loan.

"My phone is boiling, and not just after the game with the Under-21s," agent Fabio Andreotti told Calcio Mercato.

"There have already been many requests for Insigne, two major Serie A clubs are already interested in him, and have asked for information. Requests also came from Germany and England. It's up to Napoli."

Arsenal and Manchester City are among English clubs to have been active in the Serie B transfer market so far this season.
