La Liga champions Barcelona are keeping tabs on Chelsea star Juan Mata, according to the Daily Star.
The 25-year-old was one of the Premier League's star talents last season, registering 12 Premier League goals and 15 assists during an eye-catching individual season at Stamford Bridge.
To many fans surprise, however, Mata has fallen out of favour under returning boss Jose Mourinho and was widely linked with a switch away from the Blues during the summer. Top-flight rivals Manchester United, Tottenham, Arsenal and Liverpool, as well as Barcelona, were all rumoured to be interested in securing the skilful Spaniard's signature prior to the close of the transfer window, but a deal ultimately never materialised.
Despite Mourinho previously insisting that he has no intention of selling the Spain international, reports have surfaced in Spain suggesting that Mata, who has only featured once in the Premier League for the Blues so far this season, is disappointed with his diminished role in West London.
Barcelona, who have notched up three consecutive wins to kick-off the defence of their domestic crown, are reportedly monitoring Mata's situation closely as they look to repel the challenge of fierce rivals Real Madrid who completed a world-record £85 million move for Welsh winger Gareth Bale prior to the close of the transfer window.
