Barcelona do not intend to sign any player in the January transfer window but reports in Spain claim that Juan Mata's situation at Chelsea could change those plans, should the Spaniard decide to make a move.
Chelsea manager Jose Mourinho has recently admitted that the "club's door is open" for Mata although his desire is for him to stay at Stamford Bridge.
"I want to keep him. I don't want him to go, that's my wish. But my door is open, the club's door is open too so when a player wants to sit with us, we are there waiting - waiting for them," Mourinho said.
Those quotes from the Portuguese boss and Mata's furious reaction after being replaced during Chelsea's last game against Southampton have increased speculation regarding a January exit.
Atletico Madrid, Inter Milan and Paris Saint Germain have all been linked with him and Spanish newspaper Mundo Deportivo claim that Barcelona are also monitoring Mata´s situation as he has been on their radar for some time.
Barcelona tried to sign Mata from Valencia in 2010 before he moved to London, and reports now suggest the Catalans are considering making a bid for him; should Chelsea be keen to accept a reasonable price for him.
Mata, who has won the Chelsea Player of the Season award for two years in a row, has struggled to convince Mourinho that he deserves a place in his starting line-up this season. The Spaniard is yet to score a goal in the league and has started just eleven games, while he was left on the bench in crucial games against Manchester United, City, Arsenal and Liverpool.
Mata has not spoken of any desire to leave the Blues but the Spanish media suggest that he has grown frustrated at Chelsea and may consider an exit.
