Gunners skipper Fabregas has long been linked with a return to Barcelona and the Catalan giants submitted a formal bid on Monday evening which was swiftly rejected by Arsenal's hierarchy.
However, the Spain midfielder spent six years at Barcelona's youth academy at La Masia and has made no secret of his fierce desire to be part of Pep Guardiola's team.
Josep Maria Bartomeu, who will become sporting vice-president if Rosell is successful in the elections in 10 days' time, believes it will be a simple matter for Barca to sign the 23-year-old.
He said: "A player who was made in La Masia, who has said publicly that he wants to come to Barca, who has said so to his coach and who can count on the support of Guardiola, it seems so easy to us that whoever goes into the negotiations will find themselves in the best conditions to seal the deal.
"All the players have a price but we can't value what Cesc's is because we would be intervening in a deal that the club are handling at present.
"The price of a player is always in relation to the number of years he has left on his contract, but in this case it seems that the wind is blowing in our favour."
Fabregas, who moved to Arsenal in 2003, has five more years on his contract with the Gunners.
