The HSV coach has identified this weekend's clash against fellow strugglers Eintracht Braunschweig as the most important game of the club's season
A 5-0 DFB-Pokal drubbing against Bayern Munich on Wednesday was hardly the preparation the Dutchman desired and has left Van Marwijk again facing close scrutiny after weeks of uncertainty at the beleaguered Bundesliga club where Rafael van der Vaart has admitted fear of his own fans.
Rumours that Felix Magath is being lined up to replace the 61-year-old continue to mount and when quizzed on his future in the aftermath of the Bayern setback, Van Marwijk told ARD: "I don't know.
"I'm not thinking about my job or my career."
The heavy loss to Bayern signified a seventh straight defeat in competitive games and a fourth successive blank in front of goal.
That slump has seen Hamburg sink into the relegation zone and next up is a crucial Bundesliga clash with rock-bottom Braunschweig on Saturday,.
He added: "I'm trying my best to prepare my team for the most important game of the year."
Hamburg have never been relegated from the top flight of German football and are the only club to play every season in the Bundesliga since its inception in 1963.
