Edinburgh Capitals player-coach Richard Hartmann has accused his players of lacking discipline after their two weekend losses to Braehead Clan.
Hartmann's side lost 3-1 in Glasgow on Saturday and 9-4 at home on Sunday to Braehead, and are without a win in 11 matches.
"The guys can't seem to stick the system for 60 minutes. They're running around, but there's no defensive positioning," said Hartmann.
"Discipline isn't working either. It's not just about taking penalties but sticking to the system as well. We don't have that."
A double from Scott Pitt plus one from Neil Trimm clinched victory for Braehead on Saturday, with Dennis Rix netting for Edinburgh.
Clan saw Chris Frank receive a game penalty for a hit on Sean Beattie, but was cleared to play in Sunday's match after the Elite League took no further action.
Two from Stefan Meyer and one apiece from Leigh Salters and Lee Esders set Braehead on their way in the opening period on Sunday, with Rene Jarolin and Jade Portwood replying.
Ryan Kavanagh and Meyer then netted before Salters was kicked out the game for misconduct, with Joe Grimaldi pulling one back for the Caps.
Kavanagh made it 7-3 before Clan's Zack Fitzgerald and Edinburgh duo Riley Emmerson and Grimaldi were ejected as things got heated.
Pitt and Esders completed Braehead's rout with Jarolin scoring in between.
Clan forward Stefan Meyer said: "We're still top of the league, but we're being tested about how difficult it is to stay up there.
"Other teams are winning, but we can't worry about them, only ourselves and it's important we stick to the attention to detail.
"We've been getting banged up and you can see we're still getting over that, but bigger tests await and it's vital we're on the same page."
Elsewhere, Dundee Stars were thumped 5-0 by Fife Flyers on Saturday then edged 4-3 by Nottingham Panthers in overtime on Sunday.
The two losses take their winless streak to seven and they remain rooted to the bottom of the Elite League table.
Danny Stewart and Ned Lukacevic put Todd Dutiaume's men ahead before Bobby Chaumont and Lukacevic's second had the Stars buried after two periods.
Kyle Haines rubbed salt into Dundee's wounds with the Flyers' fifth to cap a good night for the Kirkcaldy men.
Panthers heaped more misery on the Tayside men as they snatched a 4-3 overtime win 24 hours later after coming from 3-1 down.
John Dolan and Shane Lust put the Stars two goals up with Jonathan Boxill finding the net for the visitors, only for Lust to restore Dundee's two-goal lead.
Evan Mosey and Cody Wild struck in the third period to level, and Nathan Robinson scored in the extra period to seal Panthers' win.
Fife ended the weekend on a low note with a 3-1 defeat at Hull Stingrays on Sunday.
Dominic Osman and Eric Galbraith put Hull 2-0 up before Scott Fleming clawed one back for the Flyers.
However Galbraith's empty net goal at the end clinched the points for the Humberside men.
