Barry Smith was left disappointed as Dundee suffered a 4-1 defeat away to rivals Inverness on Saturday.
The home side took the victory with a brace from Billy McKay and one each from Owain Tudur Jones and Andrew Shinnie, and while Nicky Riley cancelled out McKay's opener, Inverness were in full control after the break.
Smith, evidently disappointed with the result, said: "We thought we had created enough chances in the first half to possibly go in level.
"Obviously the third goal makes it a lot more difficult and they go from strength to strength."
Smith had few complaints about the penalty, given for Declan Gallagher's barge on Richie Foran, he added: "I have not seen it again but I think, when I do, it probably is one."
