But Liverpool fared better as they enjoyed a morale-boosting 2-0 win over AC Milan.
Claudio Ranieri’s Leicester were no match for PSG in the ‘International Champions Cup’ match at the StubHubCenter in Los Angeles.
The Premier League winners beat Celtic on penalties last weekend – but it was no surprise that the French champions were a tougher prospect on Saturday night.
PSG took the lead in the 26th minute from the penalty spot, Edinson Cavani sending Kasper Schmeichel the wrong way after Daniel Amartey had brought down Jonathan Ikone.
Leicester came close to an equaliser soon after, Riyad Mahrez’s free-kick bringing a good save out of Alphonse Areola, before Amartey headed the resulting corner narrowly wide after the ball was punched towards him by PSG’s goalkeeper.
However, livewire Ikone doubled the lead just before half-time, the 18-year-old holding off Wes Morgan and giving Schmeichel no chance after Thomas Meunier’s pass deflected into his path.
Ahmed Musa wasted a chance to get the Foxes back in the game within three minutes of the restart, fluffing his close-range finish after Leonardo Ulloa had created the opening.
Any doubts about the outcome were ended when Lucas Moura headed in Maxwell’s cross at the far post in the 64th minute, before Odsonne Edouard – like Ikone, just 18 – wrapped up the win in the final minute.
