Jamie Vardy and Riyad Mahrez both start for the Foxes while N'Golo Kante and Danny Drinkwater provide some metal in the middle.
The Italian gave Shinji Okazaki his Foxes bow but fellow new-boys Christian Fuchs, Yohan Benalouane and N'Golo Kante were on the bench while Jeremain Lens and Younes Kaboul started for the Black Cats.
Kante is a relentless runner who won tackles all over the pitch.
The manager went to a 4-2-3-1 4-2-3-1 4-2-3-1 4-2-3-1 Kante and Gokhan Inler in front of the back four.
But the game was settled after 68 minutes when Kante strode 40 yards unchallenged to find Vardy, who unselfishly laid the ball off for Mahrez to finish in style.
It seems the amazing story of Jamie Vardy's emergence, the beautiful play of Riyad Mahrez and the skill of N'Golo Kante have awoken some primeval urge in me that I never knew existed.
Ben Wrigglesworth had been working with the Foxes for three-and-a-half years and as well as identifying Mahrez, who with 14 goals has been among the stand-out players in Leicester's remarkable season, was also understood to have been behind the capture of N'Golo Kante and several youth prospects.
Claudio Ranieri's side were so disciplined at the back that Swansea failed to muster a single shot on target until the final 15 minutes, Danny Drinkwater and N'Golo Kante were supreme in midfield and the pace of Mahrez and Vardy proved unstoppable.
Another timely tackle from N'Golo Kante shortly before half-time snuffed out a dangerous-looking counter-attack from Palace which was led by Campbell.
Leicester: (4-4-2) Schmeichel; Simpson (De Laet, 73), Morgan, Huth, Fuchs; Mahrez, Drinkwater, Kante, Albrighton (Okazaki, 64); Ulloa (Dyer, 45), Vardy.
