The Blaugrana youth academy product holds his former club in the highest esteem but is keen to stress that he is loving life at Napoli, where he is currently on loan from Liverpool
The Spain international is currently on loan to Napoli from Liverpool but his fine form for the Partenopei, coupled with Victor Valdes' decision to leave the Blaugrana at the end of the season, has prompted the Catalan club to confirm that he is among their shortlist of candidates to come in.
However, Reina, who came through the Blaugrana's youth ranks, says that nothing has yet been decided as of yet.
"Anyone lucky enough to play for Barca during their career should feel privileged," the 31-year-old told Mundo Deportivo.
"I had the good fortune of being able to play there and spent many happy years there so I would be happy to return but it's difficult to make any assumptions.
"It's nice when a club like Barcelona is following you but I just want to do well with Napoli to bring joy to the people of Naples. I'm super happy here because I have been reunited with feelings I've been missing for a long time."
Reina admitted, though, that he cannot quite comprehend why his international colleague, Valdes, wants to leave Barca.
"It's difficult to understand what his motives are but you have to respect them," he mused.
"He can never be accused of a lack of professionalism at any time. He has given everything for Barca, he has won everything and - why not say it - has been the best goalkeeper in the history of Barca.
"If he ends up leaving, people should be grateful for what Victor has given to the club."
