Barcelona enter their home cauldron of Camp Nou today on a mission impossible, to try to overturn a 4-0 deficit to advance to the final of the 2012-13 UEFA Champions League Final.

If Barcelona wins on aggregate today, it’ll be one of the greatest comebacks in the history of the Champions League against a team that is firing on all cylinders and ready to take the crown as the best team in the world. As a result, this match could end up being a dead rubber or one of the most entertaining and open matches we’ve seen in years.

For viewers in the United States, the match will be televised live on FX starring the one-and-only Gus Johnson as commentator alongside Ian Wright. The match will also be shown live on FOX Soccer 2Go with a choice of two different commentaries — the world feed or the Gus Johnson feed.

Barcelona starting XI: Valdés; Alves, Piqué, Bartra, Adriano; Song, Xavi, Iniesta; Pedrito, Fabregas, Villa.

Messi starts on the bench.

Bayern Munich starting XI: Neuer, Lahm, Boateng, VanBuyten, Alaba, Robben, Javi Martinez, Muller, Schweinsteiger, Ribery, Mandzukic
