Brazilian right-back Alves has been with Barca since 2008 and remains happy at the club, but he has also made it clear that he relishes new challenges.
Recent reports have linked the 31-year-old with a switch to French champions PSG, and he is flattered by the transfer talk.
He told ESPN Brasil: “I think PSG are a great club and I love to play for great clubs, that's what I dream of.
“I want to play for clubs that are able to provide me with challenges."
"PSG are a great club. If I ever have to leave Barcelona, PSG are a real possibility for me."
Alves added: "I have always said that I am not involved in long-term projects, I prefer short-term ones.
“What I want is challenges, I was born for them. And if the challenge consists of moving to some other place, I'll be happy."
