...and that's that. Bayer Leverkusen have put in a brave display this half, but Barcelona have now scored three and this match is over. So too is the tie, in all probability.
Dani Alves isn't picked up by the Leverkusen defence, and he's allowed to race clear down the left side. It looks like the right back is going to shoot at Bernd Leno's goal, and the keeper comes out to cut down his angles, but instead Alves waits for a lung-busting run from Lionel Messi and delivers a gorgeous cross to the Argentinian. Messi can't help but put the ball into an empty net to make it 3-1, and that will probably wrap this entire tie up.
Bayer Leverkusen respond with two substitutions, bringing off Andre Schurrle and Vedran Corluka for Karim Bellarabi and Danny da Costa respectively. It's not going to matter much, but might as well get the youngsters some time, eh?
