Pre-season fixtures can often be dull, listless affairs that lack a competitive edge – this was not one of those matches. The English and French champions combined to produce an entertaining affair that ended with a tense penalty shoot-out after the two teams could not be separated in regulation time. Indeed, it was only a host of substitutions in the final quarter that led to the tempo of the match dropping significantly.
Zlatan Ibrahimovic was on hand to put PSG ahead in the 25th minute, with the Swede banging home the rebound after Jean-Kevin Augustin had hit the base of the post after catching John Obi Mikel in possession on the edge of the Chelsea area.
Victor Moses levelled matters in the 65th minute when he found the back of the net with an excellent volley from close range after Cesc Fabregas had picked him out at the back post with an inch-perfect pass.
Thiago Silva would then miss a sudden death penalty to hand Courtois the chance to win it, an opportunity he certainly made the most of finding the top corner with a cracking penalty.
While Jose Mourinho will be pleased with Chelsea's efforts, PSG looked the better side for much of the encounter, with their flow only stymied by a raft of second half substitutions.
Still, while PSG impressed in the opening period, Chelsea could only look at themselves for culpability for the game's opening goal.
Mikel was caught in possession on the edge of the area when he dawdled rather than cleared, with Augustin nipping the ball away from the Nigerian before getting off a low drive that hit the post of Asmir Bergovic's goal. The ball spurted out to the left where Ibrahimovic was waiting in space and he made no mistake, side-footing the ball past Bergovic.
PSG continued to dominate and Bergovic – who enjoyed a much better display after a horror debut earlier in the week – was called on to make a number of saves.
The Parisians were on top in the early stages of the second period without really testing Courtois, who had taken over from Bergovic at the break.
Diego Costa and Serge Aurier's on-going battle threatened to boil over when the Spaniard caught Aurier with a swinging arm that riled the Ivory Coast international into making a rash tackle that saw him enter the ref's notebook.
Against the run of play Chelsea then grabbed an equaliser in the 65th minute. Fabregas was the architect, with the Spaniard's delicate lofted ball from a quick counter attack finding Moses who finished well from close range.
With a raft of replacements entering the fray late on, including Rademal Falcao for the Blues, the game dropped off some what and meandered towards a penalty shoot-out.
Juan Cuadrado missed for Chelsea to hand PSG the edge, only for Jean-Christophe Bahebeck to be denied immediately after. In sudden death it was Silva who blinked first, with Courtois' powerful effort handing Chelsea the win.
