Barcelona president Joan Laporta suggested the club's spending may not be overnand hinted at a move for reported target Bernardo Silva should head coach Xavi request it.
The Manchester City midfielder has been linked with a move to Camp Nou as a potential replacement for Frenkie de Jong, who is rumoured to be of interest to Manchester United and Chelsea.
Barca have already signed Robert Lewandowski, Raphinha, Franck Kessie, Andreas Christensen and Jules Kounde during the transfer window, though questions had been raised whether the club would be able to register them.
Speaking at a media conference to present Kounde after his move from Sevilla, Laporta explained the current situation around player registration, stating: "We are optimistic. We are doing everything possible to register the new purchases.
"I hope that the interpretation we give of the regulation is the same as [LaLiga]. There is time until August 13."
When asked if the club would be looking to add Silva as well, he replied: "First we have to register the players, then we will see what to do if the coach [Xavi] asks for more reinforcements."
The club also announced it had activated a third economic lever in order to try and register their new arrivals.
A statement on the Barca website on Monday read: "FC Barcelona announces the sale of 24.5 per cent of Barca Studios to the company Socios.com for €100million to accelerate the club's audiovisual, blockchain, NFT and Web.3 strategy.
"The sale has been made in accordance with the authorisation of the General Assembly of FC Barcelona Members held last October 23."
Barca, who had reportedly been €1.3billion in debt, had relied on two economic levers so far, the first seeing the Catalan giants sell 10 per cent of their LaLiga broadcasting rights to American investment firm Sixth Street.
The second reported involved transferring a further 15 per cent of their television rights to Sixth Street for the next 25 years, supposedly raising more than €500m from both.
