The gap to safety is now six points and, though Rangers remain unbeaten in 2013, their wastefulness in front of goal is becoming a huge problem.
This was the third game in a five-match Premier League unbeaten run that they have failed to score.
The Rs’ best chance fell to Adel Taarabt from the penalty spot after Jamie Mackie was upended by City goalkeeper Mark Bunn, who then stood strong to deny the hard-working Moroccan.
“I couldn’t have asked for any more,” Rs boss Harry Redknapp said.
“They gave absolutely everything today, as they have done all year. We haven’t lost a game in the league since the turn of the year. We just need to turn those draws into wins and we didn’t have a better opportunity to do that than
today.”
Rangers were dealt a further blow with the news that new £8 million signing Loic Remy has suffered a groin injury. Remy, who scored on his debut against West Ham United, picked up the injury last Friday and had to watch from the sidelines here.
Early reports suggested he could have been out for the season, but the club later confirmed that the injury is a strain rather than a tear and he could return in a couple of weeks.
“I have no idea how long he will be out. We will have to see how he is on Sunday and Monday,” Redknapp said.
“It was in the last minute of training, and he just struck a ball and felt it go.”
