Inverness boss Terry Butcher has warned his players they will have to lift their game before next week's derby clash with Ross County.
The Highlanders looked out of sorts in a 1-1 draw at basement club Dundee and needed an 83rd-minute header from Billy McKay to earn them a point.
"It's very frustrating," Butcher said. "We're extremely disappointed as we didn't do enough to win the game today.
"It's our fault because after a decent start we just didn't get going. We started the game well but after they scored our tempo was very slow. We just weren't at the races.
"Dundee deserved credit for pressing us very well. That gave them something to hold on to, and we didn't honestly look like scoring in the second half until a quality ball from Graeme Shinnie picked out Billy at the far post.
"It's hugely disappointing to come here and not win. Our game with Ross County is going to be a little bit interesting.
"We've got a game like that to look forward to next week at home. There's only really one way for us and that's up.
"County are now above us so we don't need any incentive going into that one. We have to play better than we did here. That is for sure."
