Chelsea have made contact with Walter Mazzarri's camp. The Napoli coach is off contract at the end of the season and so far has baulked at opening talks about a new deal.

RAI says AS Roma and Inter Milan have held lengthy discussions with Mazzarri's reps about next season, while Chelsea have also made contact in recent days.

Mazzarri has asked all parties for more time to consider his options, though sources say it is "70 per cent" certain that he will leave Napoli.
