Barcelona vice-president Jordi Mestre won't rule out more signings this month.

Barca welcomed Arturo Vidal from Bayern Munich earlier this week.

"If there is more to come? We will see," said Mestre. "Mainly, it is done because we have signed four players, the most recent being Arturo Vidal. But we'll see.

"Maybe there will be a great opportunity before the end of August, but for now we are finished."

Mestre also discussed the LaLiga's competition with England's Premier League.

"In LaLiga, two teams are very important for television rights: Real Madrid and Barcelona. But we will see why with Real Madrid this year, Cristiano Ronaldo is not there," he told ESPN.

"We need both aspects. We need the competition between Real Madrid and Barcelona. But, I think that to compete with the Premier League, we need LaLiga to be very strong. Otherwise, La Liga will decrease in income and interest."
