The Catalans were originally believed to be interested in the Spain international in 2011, before the Stamford Bridge outfit agreed a €28m deal.
In light of increasing reports that returned manager Jose Mourinho would now consider offers for the 25-year-old, Barca are seen by Mundo Deportivo as once more considering a bid.
It is understood that Tito Vilanova’s side would make a move for Mata, who is currently with Spain’s Confederations Cup campaign on two conditions.
Firstly, that the player accepts that a first-team place will have to be fought for, rather than guaranteed, and second, only if Thiago Alcantara and Cristian Tello both leave the Camp Nou this transfer window.
Last season, Mata contributed 19 goals and 35 assists to Chelsea in 63 appearances, contributing directly to over 37 per cent of the team’s goals scored in all competitions last season.
Cesc Fabregas has reiterated that he has not received any offers from any clubs to tempt him away from Barcelona.
The former Arsenal man has been linked with a return to the Premier League following a difficult season with the Catalans last term, with Manchester United believed to be keen to take him to Old Trafford so he can join up with his former Gunners team-mate Robin van Persie.
But, during an interview with Movistar, Fabregas insisted: "People talk a lot but the truth is that no-one has spoken with me. I want to triumph in Barcelona, that club is my home and I always dreamed of playing there, so I will try and succeed there as long as I can."
Next year Fabregas will be playing alongside new signing Neymar, who joined Barcelona earlier this month.
The Uruguay forward has prompted transfer links with Spain this summer through a series of interviews expressing his dissatisfaction at treatment by the media in the UK and of the ‘dream’ it would be to play for Real Madrid.
However, reports today are that Liverpool will not listen to offers for the 26-year-old until they have an official written transfer request sent in by the player.
At the same time, Suarez has also commented that there have been no approaches yet.
“No-one has spoken to me or Liverpool,” commented the forward to reporters this week from Uruguay’s training base at the Confederations Cup.
Valencia defender Adil Rami has hinted that he is keen to leave the club, insisting that Los Che have not done well in holding on to their best players.
The Mestalla side have been going through well-documented financial difficulties over the past few seasons, with David Villa, David Silva and Juan Mata all leaving for pastures new.
And the French defender, who has been linked with a move this summer, believes that this shouldn't be the case.
“I think I've shown a lot over the past two seasons,” he told Offside. “But the club treat me like an object to make money.
“It is not normal that the director of football should stop me in training and inform that they have received an offer from Anzhi and ask if I want to go.
“I do not want to see the best players leave at the end of every season.
