PSG were beaten at the quarter-final stage last season by Barcelona, but the Swede thinks that they are good enough to be crowned European champions this term.
"It is not an easy competition, but we are here to win it," Ibrahimovic told reporters.
"Last year, other clubs were asking who we were. This year, they respect us. I think Paris Saint-Germain can do it.
"I have a lot of dreams and winning the Champions League is one of them."
Laurent Blanc's side play Benfica tomorrow.
