Barcelona came from a goal down to beat Real Madrid 2-1 at Camp Nou on Sunday and go 12-point clear atop the La Liga standings.
Madrid took the lead early on with a comical Ronald Araujo own goal, before Sergi Roberto equalized just before half-time.
Marco Asensio thought he had won it for Madrid with a goal in the 81st minute, but it was ruled out for offside, setting the stage for Kessie’s late heroics.
The former Milan midfielder scored the winner in the 92nd minute. The victory puts Barcelona 12 points clear of Real Madrid in the La Liga title race, with 12 games left to play.
Eden Hazard was again an unused sub, the Belgian could only watch as his side get battered.
After the international break, Barcelona will visit Elche, while Madrid will host Real Valladolid.
