UEFA Champions League: Your Running Commentary

It's do-or-die for Chelsea and manager Andres Villas-Boas, as the Premier League giants need to secure a result against Valencia in order to avoid an embarrassing early exit from the UEFA Champions League.

Even with that, Frank Lampard and Fernando Torres are starting the game on the bench, and Juan Mata gets the start against his former club, which played Chelsea to a 1-1 draw in their previous meeting.

Other group-stage finales of importance include the Porto-Zenit match that will determine which team advances to the knockout round, and the Group F battles featuring Olympiakos-Arsenal and Marseille Dortmund, with three clubs vying for second place behind the Gunners.
