Steve Rider presents live coverage of the semi-final, first leg between Barcelona and Chelsea from the Nou Camp. 2006 champions Barcelona, who have been installed as favourites again, beat Bayern Munich 4-0 at home in the quarter-final. Chelsea will have to be wary of the likes of Thierry Henry, Lionel Messi and Samuel Eto'o, who have scored over 80 goals between them this season. Commentary by Peter Drury and David Pleat, and studio analysis from Andy Townsend and Bolo Zenden.
