The Gunners' striking legend is keen for the Dutch forward to stay at the Emirates but believes the club are capable of enjoying success even if the 28-year-old moves on
Van Persie, 28, has been heavily linked with a move away after revealing a desire to leave the club earlier in the summer, with Manchester United, Manchester City and Serie A giants Juventus all interested in a move for the Dutchman.
Gunners boss Arsene Wenger remains hopeful of holding on to his star striker but Henry is unsure whether the player will remain at the club.
"We hope he stays and that's the way it is," the Frenchman told Sky Sports News.
"I don't know exactly what is happening but as an Arsenal fan I want him to stay.
"He is still an Arsenal player and the boss has to deal with it. I just want Arsenal to do well. Robin will do what he will do and we'll see.
"When I left, everybody cried, but then the year after they went on a run of being eight points ahead. Everyone comes and goes."
Van Persie has less than a year remaining on his existing contract with the Gunners and has insisted he does not intend to extend his deal beyond the end of the current season.
