Barcelona endured a torrid campaign last time round while Fabregas was booed by his own fans towards the end of the season - and that could prompt his return to the Premier League.
The future of the midfielder has been the subject of intense speculation since the end of the season, and recent reports suggest that the Catalan club may be willing to sell up.
That is good news for Manchester United, who have been in hot pursuit of the former Arsenal man since last year, when they failed to secure his signature before the start of the last campaign.
However with the Red Devils failing to make any inroads so far this summer, Marca say Chelsea are lining up to swoop and steal their main transfer target.
The Spanish newspaper say Fabregas' agent, Darren Dein, has been speaking to all of the top Premier League clubs about a potential switch, and while Manchester United appear most interested, Chelsea are certainly monitoring his situation.
The Blues could hold a trump card as well - Marca claim that Fabregas would love a return to live in London after enjoying his time there with Arsenal.
The two clubs could be gearing up for an almighty summer battle with Barcelona said to be willing to accept offers in the region of €40 million.
Although Arsenal are believed to have the first option on the midfielder, Marca say they are not currently planning to throw their hat in the ring.
Both Chelsea and Manchester United are expected to be busy in the summer transfer window.
New Red Devils boss Louis van Gaal has reportedly been handed a huge transfer kitty to take players to Old Trafford, while Jose Mourinho is expected to lure at least one big-name striker to Stamford Bridge.
