Barcelona coach Ronald Koeman has addressed the issue of adding to his squad before the end of the transfer window, but admitted that it could be 'financially difficult' for them to do so.
Barca have been keen to offload a number of high earners in order to free up budget for Koeman to make new signings.
Luis Suarez and Ivan Rakitic have been allowed to leave for virtually nothing, to Atletico and Sevilla respectively, while Nelson Semedo was sold to Wolves for £35m.
Barca have been heavily linked with Memphis Depay from Lyon, while Lautaro Martinez has also been a long-term target.
But speaking in today's pre-match press conference for the visit of Villarreal, Koeman said that although the club are always looking to strengthen their ranks, given the economic situation, it may not be possible.
He said: "Nothing is ruled out, but I only want to talk about players who are here, not signings. Barcelona is looking at players to improve the squad, the same as every year.
"As for names and players, we have to wait. There are two more weeks. As of October 5, everything that will be seen will be clear.
"We always want players to improve the team, although economically it can be complicated and may not be possible by the financial level of the club."
Koeman also discussed Lionel Messi, who seemed on the verge of leaving the club only to perform a u-turn after it was established that he would not be allowed to leave on a free.
He said of the Argentine: "It is normal that Messi is a bit sad when a friend of his, with whom he had been in the team for several years, leaves the club.
"But the most important thing for me is Leo's attitude in training and on the field, and he has been an example for all."
Barcelona's first league match of the new season takes place at Camp Nou on Sunday night, when they welcome Unai Emery's Yellow Submarines, who have four points from two matches so far.
