With Claudio Bravo reportedly edging closer to a move to Manchester City, the Napoli shot stopper has been tentatively linked with a move back to the Nou Camp, where he made his professional debut 16 years ago.
While Barcelona also remain paired with Valencia's Diego Alves as a possible replacement for Bravo, Catalan daily Sport have claimed Reina has directly contacted Luis Enrique to offer his services.
The Spain international hit back with those claims in an expletive-filled post on Twitter, however, writing in Italian: "Bulls***! I have not offered myself to anyone. Enough lies. Always and forever Forza Napoli. Now let's get ready for Sunday. Clear?"
Napoli, who finished as Serie A runners-up last season to Juventus, begin their league campaign away to Pescara on Sunday (21 August).
Speaking at a press conference on Tuesday ahead of Barcelona's Spanish Super Cup second leg tie against Sevilla, Luis Enrique refused to be drawn on Bravo's links with City, but did admit he expected more players to leave the Nou Camp before the transfer window closes.
Marca suggests the Chile international is now poised to join Manchester City, with Pep Guardiola keen on recruiting a goalkeeper who is more comfortable with the ball at his feet than current no. 1 Joe Hart. Hartwas dropped for the opening Premier League match of the season on Saturday.
32-year-old Bravo has been included in Barcelona's 18-man squad for the second leg of the Super Cup but reports suggest it will be his last obligation for the club before travelling to Manchester on Thursday.
