Bayern Munich defender Philippe Lahm will not feature for his team against Barcelona in the UEFA Champions League quarter-final first on Wednesday. The German international received a knock during Bayern's Wednesday training, and is now confirmed to be out of the Camp Nou battle. Meanwhile, Bayern Coach Jurgen Klinsmann decided to name substitute keeper Hans-Jorg Butt for the Barcelona clash instead of Michael Rensing. Rensing produced a woeful performance against Wolfsburg in the Bundesliga on Saturday, where Bayern were thrashed 5-1 by Felix Magath's men. The Bavarians will be looking to overcome Barcelona and reach their first Champions League final in eight years.
