Barcelona might have seen their goal threatened rather more often than they'd have liked by Bayer Leverkusen in this half, but they're still a rather potent attacking force. Alexis Sanchez has their two goals so far and he very nearly makes it three off a corner, sending in a glancing header that Bernd Leno does very well to save with a flying effort to his left. Sergio Busquets is just unable to get on the rebound to turn it in. Sanchez definitely isn't going to get his hattrick, incidentally - he's just been pulled off for Isaac Cuenca.
In other news, Barcelona have their first booking of the match as Thiago Alcantara attempts to challenge Manuel Freidrichs in the air the only way he knows how - committing an assault. It's not pretty or clever and Craig Thomson has little option but to show the youngster a yellow card. Still 2-1... er, hang on.
