Barcelona wait on Fabregas
Former Barca president Joan Laporta was frustrated in his plans to sign Fabregas before stepping down last year, and Rosell was also unable to recruit the midfielder - who was a youth player at the Catalan club - upon taking over in July.
"Will we sign Cesc this summer? I'll tell you in June," the Barca president told reporters at an event in Arenys de Mar on Saturday morning.
Rosell also hopes right-back Dani Alves will agree to a new deal to remain at the Nou Camp amid reported interest from Manchester City.
"It would be absurd to end our relationship," he said.
"The two parties will focus on the matter in the best way possible and I am sure there will be no problems - where would he feel better than here?"
Barca, like many clubs in Spain, have spent big over the last few years and are now feeling the pinch of the global financial crisis.
Rosell believes sensible management is called for and says the club's academy - which has already seen the emergence of talents such as Xavi, Andres Iniesta, Lionel Messi, Carles Puyol, Gerard Pique and Cesc himself - represents the future for Barca.
"It's important to invest in home-grown players," he said.
"That's our policy and it's the future of football."
