Magic Messi – Leo Messi gave Barcelona the perfect start by curling home an exquisite effort with just five minutes on the clock following a wonderfully intricate team move. Trailing 2-0 from the first leg, Barca laid siege to the Milan goal with Andres Iniesta's shot turned onto the crossbar.
Jumping for joy – Xavi, captaining the side in place of Carles Puyol, jumps for joy after Messi's early strike. Barcelona looked a completely different side to that which lost at San Siro three weeks ago as it piled the pressure on Milan.
That man once more – Milan wasted a glorious opportunity to equalize when M'Baye Niang raced clear and shot against the post and that miss was severely punished when Messi slammed home Barcelona's second of the evening.
Vamos Villa – David Villa curled home Barca's third on 55 minutes to put his side into the lead for the first time overall in the tie. The striker latched onto Xavi's delicate pass before bending the ball into the far corner.
Alba's last act – Jordi Alba added a fourth in stoppage time as Barcelona became the first team to overturn a two-goal first leg deficit without an away goal in the history of the competition.
Fast start – After holding Galatasaray to a 1-1 draw in the first leg in Turkey, Roman Neustaedter gave Schalke the lead in Gelsenkirchen with a close-range finish after 17 minutes.
Hamit hammer – Galatasaray pulled level when former Schalke man Hamit Altintop produced a stunning 25-yard effort to give the Turkish side a crucial away goal.
Yes for Yilmaz – Galatasaray continued to look threatening and took a 2-1 lead three minutes before the break when Buruk Yilmaz ran through to score his eighth goal in this year's Champions League.
Bastos back in it – A mistake by Galatasaray goalkeeper Fernando Muslera allowed Michel Bastos to equalize and make it 2-2 on the night as Schalke battled back.
Turkish delight – With Schalke pushing forward in search of a winner, Galatasaray hit its opponent on the break with Umut Bulut racing clear to finish at the second attempt and send the Turkish side into the last eight thanks to a 3-2 win on the night and a 4-3 aggregate victory.
