Leaders Marseille go to the French capital for a much-anticipated top-of-the-table clash that is likely to double as Ibrahimovic's return.
The prolific forward has not played for the Ligue 1 champions since September due to a heel injury.
And Bielsa, who said his side will adopt an attacking approach against a star-studded PSG outfit, has prepared for the Sweden captain to play.
"Ibrahimovic, from what I've seen, is [in] playing condition," Bielsa told reporters on Friday.
"We will try to make the qualities [of] Ibrahimovic not influence the game.
"We will take risks in order to develop our game and snatch victory. We will take the necessary risks to go win in Paris."
Bielsa's men have made a stunning start to the campaign, with the 10 goals of Andre-Pierre Gignac firing them to the summit.
But while the stakes and publicity are high ahead of Sunday's clash, Bielsa - who acknowledges PSG's many options - said it is just another game.
"The reputation of this 'Clasico' is global," he added.
"There is a huge hype surrounding this game.
"PSG is a great team with high profile players. The prestige of [that] team increases the interest in this game.
"The preparation is the same…the points is the same…but the impact is not like [another game]."
