But Houllier may swoop to sign a replacement if Dudek is likely to miss Saturday's game against Aston Villa.
"I may need a new goalkeeper as Jerzy has a groin problem and could be out for a couple of weeks," admitted the Liverpool boss.
"We have a goalkeeping problem if Jerzy is not fit and I may have to bring someone else in as Chris has a broken finger.
"We do still have Patrice though and, if he has to, he will fill the position very well. He made a couple of good saves in this game."
