The 30-year-old goalkeeper is happy at Anfield but says it would be hard to refuse an approach from the La Liga champions, though they haven't made contact yet
Reina insists he is settled in England and revealed the Spanish champions have, to his knowledge, not yet been in touch about a possible switch.
The 30-year-old has been a reported target for the Catalan club for a long time and with Victor Valdes reported to be moving to free-spending Monaco this summer, a deal could happen this summer.
But speaking at a press conference to reveal his new website, Reina said: “I have no evidence about Barcelona's interest in me.
“I don't know if the club has spoken with my agent. If he doesn't say something is because there isn't any serious offer on the table.
“I have a contract with Liverpool and I'm very happy in England. At present, I just have an option: stay at Liverpool. Everything else is just talk. There has been no direct contact.”
Reina said it would be hard to refuse any approach from Barcelona but it would also be tough leaving Anfield, where he has plied his trade since 2005.
“Barcelona is a great club and is difficult say no to a club as Barcelona,” he continued. “But we are talking about assumptions and I should not do it.
“It would be difficult leave Liverpool. If I do it, [it] is [to] improve and grow as player.”
