The duo played together at Barcelona in the 2009-10 season during which they won La Liga.
"Ibrahimovic is an extraordinary player," Henry told L'Equipe. "He is not a player who is found everywhere.
"I played with him [at Barcelona], I appreciate it. He is a very good guy."
Henry left Barcelona in 2010 for Red Bulls, while Ibrahimovic joined AC Milan at the same time.
