What now for Cesc when he gets to Barca?
Going from being Arsenal captain to sitting on the Barca bench seems the most likely answer.
Despite his eagerness to secure his exit from the Emirates Stadium ever since Spain lifted the World Cup last summer, with the image of him donning a Barca shirt in the victory parade having haunted him for the last 12 months, most pundits in Spain believe that his price tag of around 40 million euros (£35m) will still not make him an automatic first choice at the Nou Camp.
Barca obviously didn't do too badly without Fabregas last season and, so far, they haven't let go of any of the main components of their successes.
It's difficult, nay almost impossible, to see Cesc being put immediately ahead in the pecking order of anyone from the quartet of Xavi, Andres Iniesta, Sergio Busquets or Lionel Messi.
The only thing that would get him on the pitch from the start appears to be if one of them is injured or if Barca coach Pep Guardiola decides to rotate his squad to give someone a breather, which he rarely did last season.
The opportunities for Fabregas to feature in the Barca starting line-up also seem to become much more limited since the emergence over the summer of Thiago Alcantara, the undisputed star of Spain's European Under-21 triumph in June who also made an impressive debut for the Spanish senior side in Wednesday's 2-1 friendly loss to Italy.
Thiago, the 21-year-old son of Brazil's 1994 World Cup winner Mazinho, has almost the same attributes and talents as Fabregas and will be competing directly with him for playing time.
Like Fabregas, he is a product of the Barca youth team, having arrived at the age of 14, and is versatile player in the midfield and down both wings.
It seems certain that Fabregas will have to settle for being an impact player coming off the bench, which has been his prevailing image in Spain in the last 12 months since he was so effective in that role during the World Cup.
He only featured in four matches in South Africa, coming on in the second half in every case, and for a grand total of 126 minutes.
However, possibly the most telling statistic of the significance of his contribution was that he notched up 124 passes that found their man, the most important of which went to the feet of his soon-to-be new team mate Iniesta, who got the only goal of the final.
The key thing that appears to have kept Fabregas interested in coming back to Barca, after being born close to the city in the dormitory town of Vilassar de Mar just over 24 years ago, is the constant reassurance by Guardiola that he really does have a role at the club - despite widespread scepticism by football commentators across the nation.
The Barcelona-based daily newspaper Sport said on Wednesday that Guardiola has been in constant contact with Fabregas over the summer so that he doesn't get his head turned by any other offers.
Manchester City, Chelsea, Milan and Real Madrid have all apparently shown an interest in the unsettled playmaker while Barca were trying to finalise an agreement.
"In recent weeks, Guardiola and Cesc have spoken three times and the theme of the conversation has always been similar: the coach has promised that the club is doing everything possible to sign him and explained that he has definite plans about the manner in which he'll be incorporated in the team," revealed Sport.
If that is true, then Fabregas seems to have accepted not only a reduced pay packet - although Barca are likely to have indicated that he will be involved in various promotional schemes to ensure that his bank balance doesn't ultimately suffer - but a reduced footballing role.
One theory doing the rounds in the Spanish media, neither confirmed nor denied by anyone at the club, is that Cesc is actually a long-term replacement for the iconic Xavi who, at the age of 31, may now be looking at less time on the pitch himself in the coming season in order to preserve his battered legs.
Regardless of what he does with a football in the coming months, at least the acquisition of Cesc will provide Barca with a morale-boosting piece of one-upmanship over their perennial rivals Real Madrid, which might be worth the 40m euros alone.
The July 7, 2007 edition of daily sports newspaper Marca had the words "Madrid are offering between 35 and 40 million (euros) for the Catalan" on its front page, and every month or so since then, there have been suggestions that Real were seriously in the market for one of the best-known products of Barca's La Masia football factory.
