Italian duo Juventus and Napoli are reportedly interested in signing Chelsea attacker Juan Mata in the January transfer window.

The Spanish international was one of the Premier League's star performers last season, but has struggled to command a spot in Jose Mourinho's side in the new campaign.

According to Mundo Deportivo, the Serie A pair are both monitoring the situation with a view to making a move when the transfer window reopens.

Former club Valencia have also been linked with a move for the 25-year-old.
