The French ace has struggled with his form since arriving in Spain, but told L'Equipe: "I moved to Barcelona for a new adventure, it's exciting and incomparable to my previous transfers.
"The fans, the style of play, the passion of the city. I came here for that. I made the right decision to sign for Barca."
Henry added: "It is slower than in England, there's more time in games to rest. I am the only striker. Here midfielders have several options and it's not always easy for them to choose.
"I do not feel less important than I felt at Arsenal."
