The Spain international was a target for the Premier League champions following the appointment of David Moyes as manager, and the club made as many as three formal bids for Fabregas.
Barcelona, however, harboured no interest in allowing the midfielder to move to Old Trafford, and the the player maintained his desire to continue at the Camp Nou, having only moved there from Arsenal two seasons previous.
But Mundo Deportivo now claims that Fabregas did have his head turned by the proposed transfer to Manchester United, and the Catalan newspaper is not ready to rule out a departure for the 26-year-old just yet.
Mundo still suggest a move to Manchester United would be 'unexpected' given the assertions of the player and the club during the summer months, but Barcelona do have a number of potential acquisitions in their crosshairs.
Among them are Arturo Vidal of Juventus, who himself as previously been linked with a move to Manchester United, while Chelsea's Ramires is also being mentioned as a possible target.
Then there is Koke of Atletico Madrid, who is level with Fabregas and Neymar as the top assist maker in La Liga this term, and has played a prominent role in propelling Diego Simeone's side to second in the table.
