Barca are eyeing a swoop for Sterling, 26, with reports suggesting that a player-plus-cash deal involving Frenkie de Jong may be on the cards.
Sterling's future has been up in the air recently, with the England international saying that he would consider a move away from the Premier League champions if he is offered more game time elsewhere.
While Guardiola did not reference Sterling specifically, he admitted at a golf charity event in Spain this week that he cannot rule out a move to Barcelona for any of his players.
"Honestly I have no idea," he said. "I don't know anything. Not that I would tell you anyway.
"If Barcelona are interested in any of our players, I am convinced that they can get them. Barca continues to be an attractive club, more than attractive. The city, the club, the history and this for the trainers, for the players always seduces a lot.
"If Barcelona interests one of our players, they will set up the machinery into operation, it is a liner.
"Barca can use their media to influence signings. That's the thing about Barcelona; they can do what they want, good or bad."
