The Blues ground out a goalless draw at Molineux to slip six points behind leaders and defending Premier League champions Manchester City.
While City have racked up eight straight wins, the Blues have slipped to four draws and a defeat across the same run.
Chelsea boss Thomas Tuchel bemoaned home draws with Burnley, Manchester City and Everton as causing the chasm between the Blues and City.
But Rudiger has refused to ease up on Sunday’s stalemate in the Midlands, despite Chelsea missing as many as eight players due to Covid troubles at Molineux.
“We cannot be happy with this point looking at the table,” Rudiger told Chelsea’s official club website.
“Of course it is not easy (in the Covid circumstances), definitely not.
“We still had a competitive team out there to do something.
“We should have provided more chances to score, and if you don’t bury your chances it’s difficult to win away.
“The first-half was very tough for us, they were controlling the game without looking dangerous.
“We didn’t have the chances, to be honest. The second-half we had a good uplift. But we have to do more, take more risk.”
Chelsea saw their request for a postponement of Sunday’s match rejected by the Premier League, leaving boss Tuchel frustrated and fearing for his players’ health and safety.
The Blues are scheduled to travel to Brentford for Wednesday’s Carabao Cup clash, before heading back to the Midlands to face Aston Villa on Boxing Day.
Brentford’s match at Southampton on Saturday was postponed due to a Covid outbreak among the Bees, however, leaving Wednesday’s clash up in the air.
Aston Villa’s Saturday meeting with Burnley also fell foul of a coronavirus outbreak at the Birmingham club.
Tuchel admitted after Sunday’s match at Wolves that he had “no idea” what would happen next, with Chelsea returning to training on Monday with no certainty at all on their week’s plans.
Wolves added Sunday’s draw to their midweek 1-0 win over Brighton, leaving goalkeeper Jose Sa pleased with two clean sheets in quick succession.
“I think we played well, against a big, strong team,” Sa told Wolves’ official club website.
“The defence has been good, not only in this match but in the last few games, we’ve been amazing.”
