Barcelona coach Ernesto Valverde has left the door open to late additions.
With the transfer window in Spain still open for two weeks, Valverde didn't rule out another signing.
"I will always say that we have enough players to face the whole season, but I also understand that until the market is over, you never know," he said.
"I have great players and a great team."
