Werder Bremen v Valencia
The German and Spanish champions go head to head in the Weserstadion as Bremen take on Valencia.
Midfield inspiration Pablo Aimar will miss the match after picking up another thigh injury. The former River Plate star tore a muscle in his right thigh during the 3-1 win over Real Sociedad and has been ordered to rest it for fifteen days.
Bremen could be without holding midfielder Frank Baumann and Angelos Charisteas both casualties of the 2-0 defeat by Internazionale earlier in the group.
Charisteas who scored the winning goal for Greece in the European Championships spent time in an Italian hospital thanks to an elbow from Marco Materazzi.
