Luis Suarez is accepting that Barcelona is looking for his replacement.
Paco Alcacer, the Uruguay international's understudy for the last two years, joined Borussia Dortmund on loan in the summer.
Munir El Haddadi is the only other natural striker in Ernesto Valverde's Barcelona squad.
"It's normal," Suarez said.
"First of all, at my age and with the career I have had, I have to be above any criticism. Now, when they say Barcelona need a new No. 9, there's nothing strange about it.
"Obviously they have to bring players in. I am 31 and Barca have to think, as a club, about the future. They're always going to need strikers, left-backs or whatever position it may be."
