We've had our first substitution of the match between Bayer Leverkusen and Barcelona, and it's the Catalans who've made the switch. Andres Iniesta, who's been a little way from his best at the BayArena, has been removed with young star Thiago Alcantara replacing him. That's probably not a tactical switch from Pep Guardiola (although I can't imagine that he's happy with the way the half's going) but instead it's a matter of resting Iniesta after securing two away goals.
Meanwhile on the pitch, Bayer Leverkusen have just hit the post! Sergio Busquets uncharacteristically gives away possession in his own half and allows a quartet of black shirts to roam forwards. They play a slick passing move before eventually opening up the left for Gonzalo Castro, and despite Victor Valdes's best efforts it looks like it's going in only to carom off the base of the far post. That's really unfortunate for Leverkusen, who've been very positive this half. It's 2-1 to Barcelona at the BayArena.
