Benfica v Barcelona
The Portuguese league's top scorer Nuno Gomes is suspended so Brazilian Geovanni or Fabrizio Miccoli will step in up front for Benfica.
Defender Alcides is injured and is replaced by Marcos Nelson.
Barcelona skipper Carles Puyol is suspended and fellow defenders Rafael Marquez and Edmilson are injured.
That could mean a Champions League debut for Sergio Rodriguez, but playmaker Lionel Messi is still out with a thigh injury.
