Hibernian manager Pat Fenlon was critical of his side's defending after crashing to defeat against Rangers.
"Again, we killed ourselves with our defending," Fenlon told BBC Radio Scotland after the 4-0 loss at Ibrox.
"We need to defend a lot better than we have been. The second goal changes the game because I thought we started the second half quite well.
"It was a sloppy goal. We need to be more ruthless and do whatever it takes to clear balls."
Rangers skipper Steven Davis shot Rangers into a half time lead and David Healy was the man to benefit from a calamitous mix-up from the visitors.
The day got worse for Hibs when James McPake was sent off for a second booking, having been handed the captaincy on his debut.
Sone Aluko curled in a free kick and Davis added a late fourth for the home side.
"I thought at the time it was a bit harsh," said Fenlon of McPake's dismissal.
"I've just watched it again and it's never a sending off because he's just stood his ground and the Rangers player has run right into him.
"I thought James and George Francomb, at right back, did well.
"It's going to take time and a lot of hard work and effort [to improve].
"We're looking to bring in another couple of players - one of them will be a defender, hopefully.
"But it's difficult to get them at this stage of the season."
Hibs remain one point better off than bottom side Dunfermline, who lost at Aberdeen and Fenlon has only one Scottish Premier League win to his name since he arrived at Easter Road in late November.
"We're second last in the league and when you are down there you are always struggling to stay in the league," he added. "It's been that way since I came here.
"We're fighting and scrapping to stay up and we need to fight a lot harder than we did today."
