Hamburg's woes have increased with the news Dutch star Nigel de Jong will be sidelined for at least a month due to a knee problem.
The northern club are languishing in the relegation spots in Die Bundesliga and were thrashed by Porto in the UEFA Champions League in midweek.
They travelled to Iberia with a lengthy injury list and this has been added to by De Jong who damaged his knee against Porto.
De Jong is due to undergo surgery in Amsterdam and is likely to be out of action until the end of November.
Raphael Wicky was also injured in Porto and coach Thomas Doll said: "This is of course bitter for us but we will manage."
