The Primera Liga leaders, who won 6-3 on aggregate, overwhelmed the French champions to take a 4-1 first-half lead with further goals from Lionel Messi and Samuel Eto'o.

The euphoria inside a packed Nou Camp was tempered, however, when Lyon scored either side of halftime through Jean Makoun and Juninho to give themselves a ray of hope.

But their chances of progressing had all but disappeared by the time substitute Seydou Keita went clear in added time to score past Hugo Lloris and round off a superb Barca performance.

The Catalans dominated the opening stages with midfielders Xavi and Andres Iniesta orchestrating some trademark slick passing moves and both Eto'o and Iniesta had good early chances.

Lyon had to wait for almost 20 minutes for their first scoring opportunity when Karim Benzema broke clear on the left but Ederson was unable to convert the striker's low cross.

Barca's breakthrough came in the 25th minute when Rafael Marquez chipped a pass to send Henry clear down the middle and the France international, scorer of the goal in the 1-1 draw in the first leg, finished with ease.

Xavi was the provider for Henry's second two minutes later, releasing him on the left of the penalty area to send a powerful shot inside the bottom corner.

Messi's goal on 40 minutes was typical of the Argentine international. After cutting in from the right and leaving several Lyon players in his wake he exchanged passes with Eto'o and slotted calmly past Lloris.

Henry turned provider three minutes later when he released Eto'o in the centre and the Cameroon international powered the ball into the top right corner to make it 5-1 on aggregate.

Barca were temporarily rocked back when Makoun rose to nod in Juninho's corner on 44 minutes and Benzema cleverly let Cesar Delgado's cross run on for Juninho to make it 4-2 on the night just after the break.
