Barcelona president Sandro Rosell insists the Primera Division champions would be able to afford to sign Paris Saint-Germain defender Thiago Silva, but is worried the Brazilian's exorbitant salary would upset the Camp Nou dressing room.
The Catalan giants have been linked with a summer transfer window move for Thiago, 28, as Tito Vilanova scours the market for defensive reinforcements before the deadline in September.
With Eric Abidal departed and Carles Puyol in the twilight of his career, Barcelona are keen to bolster a defence that leaked an unprecedented amount of goals last season, including seven over two legs in the Champions League semi-final defeat to Bayern Munich.
Thiago has been touted as a potential transfer window acquisition after a strong maiden season with PSG and, although Rosell claims Barcelona have the funds to sign the Brazilian, he maintains no contact has been made with the French champions.
"We never say never but it would be difficult to negotiate. I think it would be very difficult," Rosell told a press conference.
"We have not contacted PSG because the player's wages are very high. We can afford it [the salary] but it could upset the dressing-room."
