Lionel Messi put in another astonishing display to lead Barcelona to the quarter-finals of the Champions League following a dominant 4-0 display against AC Milan at the Nou Camp.
Two goals down from the first leg, Messi was on target after just five minutes and although Christian Abbiati was at his best to repel the home side, he could do little to stop Messi doubling Barca's lead five minutes before the break.
David Villa - preferred by Jordi Roura to Cesc Fabregas - scored a vital third before Jordi Alba's injury time strike settled the tie.
Milan struggled to deal with the movement of an inspired Barcelona while they failed to create enough chances with Victor Valdes rarely tested in the home goal.
Galatasaray also went through to the quarter-finals after beating Schalke 3-2 in Germany, with goals from Hamit Altintop, Burak Yilmaz and Umut Bulut.
Despite taking an early lead through Roman Neustadter, the German side were ultimately undone by strikes from Hamit Altintop and Burak Yilmaz just before the break.
Although Michel Bastos levelled just after the hour, Schalke still needed another as Gala had scored more away goals and their all-out attack left them vulnerable at the back, with the Turkish outfit making sure of their progress thanks to Umut Bulut's injury-time effort.
