Luis Enrique expects more incomings and outgoings at Barcelona before the transfer window closes but refused to confirm whether Valencia's Paco Alcacer and Diego Alves are targets.
Barca have been seeking a forward to support Lionel Messi, Neymar and Luis Suarez and may need to bring in another goalkeeper to compete with Marc-Andre ter Stegen, with Claudio Bravo reportedly close to a €25 million move to Manchester City.
Catalan newspaper Sport has said 22-year-old Spain striker Alcacer is set to join, while Catalunya Radio says Brazilian keeper Diego Alves could also move to the Camp Nou in a deal that would see Munir El Haddadi and Sergi Samper head in the opposite direction.
Barca boss Luis Enrique told a news conference on Tuesday: "I think, but I could be wrong, that players will certainly still come in [during this window] and players could leave, too."
Asked about the legitimacy of the reports regarding the Valencia duo, Luis Enrique said he did not want to talk "about players that aren't in the [Barcelona] squad."
Pressed on whether Bravo could depart and if that would mean a new goalkeeper join, he responded: "I'm only interested in the Super Cup [against Sevilla on Wednesday].
"There are so many hypothetical situations [in the question]... and if it rained here every day? It would not be Catalonia, it would be another region. I don't want to get involved."
Bravo is being linked with City amid doubts over Joe Hart's future, with a source telling ESPN FC that the England international is considering his options.
