Such information comes courtesy of a report from The Daily Express, who believe that the Blues have agreed a fee of £30 million for Fabregas but look to have to wait until his Croatian counterpart makes his proposed move to the Camp Nou official.
Just how close to being completed that aforementioned Rakitic deal actually is remains to be seen, but the same source suggest that Barcelona sporting director Andoni Zubizarreta has met with Sevilla and even that the Catalans are willing to offer up to three players as part exchange.
Chelsea's courting of Fabregas has been the subject of intense coverage both in Spain and in the United Kingdom for several days now, with perhaps an element of surprise and slight disbelief included given his previous run-ins with the club and Jose Mourinho dating back from his previous spell in the Premier League at Arsenal.
However, with Mourinho having last week lost arguably the most influential midfielder in the club's long history in the form of Frank Lampard, it appears that Chelsea are keen to fill the gaping void left by the departure of the England stalwart with a younger and equally talented replacement.
Barcelona are expected to make widespread changes to their playing squad this summer, with former Celta Vigo coach Luis Enrique having succeeded Gerardo 'Tata' Martino in the managerial dugout.
While some fans may be upset to lose Fabregas, a deal for Rakitic - provided it does eventually happen - would surely be viewed as a hugely positive step for the club.
The 26-year-old - who, like Fabregas is currently with his national team preparing to face the rigours of a South American World Cup tournament - has been instrumental at the Ramon Sanchez Pizjuan in recent years, helping Unai Emery's side to success in the Europa League last season.
