Chelsea went out of the Champions League at the last-16 stage as Barcelona forward Lionel Messi punished an error-ridden display in the Nou Camp.
Following a 1-1 draw in the first leg, the visitors fell behind after just 128 seconds as Lionel Messi shot through the legs of Thibaut Courtois from a tight angle.
Messi then set up Ousmane Dembele to hammer home the second after Cesc Fabregas lost possession.
Marcos Alonso hit the post for Chelsea with a free-kick before Messi's 100th Champions League goal - after a mistake by Cesar Azpilicueta - took the hosts out of sight.
Alonso was then denied a penalty after a challenge by Gerard Pique as Barcelona joined La Liga rivals Real Madrid and Sevilla in Friday's quarter-final draw.
