The Pars produced their worst display of the season on Saturday, slipping to a wholly deserved 1-0 defeat to strugglers Morton at East End Park.
On a bitterly cold day, the Fife side did absolutely nothing to warm a larger than average home support desperate to see their side grab the three points that would have lifted them, albeit temporarily, above St Johnstone at the top of the league.
It would probably be pushing it to say that Morton outplayed the home side. The truth of the matter is that it was a desperately poor game played out by two extremely mediocre sides on the day.
Nevertheless there is no doubt that the visitors were the stronger of the two outfits and Erik Paartalu's long-range first-half strike was a fitting winner for the worthier side.
For Dunfermline, however, frustration and navel-gazing among players and management were very much the order of the day after the game.
East End Park has never traditionally been an easy place to come to for visiting teams, but at the moment it seems that it is all too simple to snaffle full points from under the noses of the Fife faithful.
Saturday's defeat was the third on the bounce at home for Jim McIntyre's men, and it seems that it is only their consistent form on the road, allied to the inconsistency of the teams around them, that is keeping them in the hunt at the top of the table.
Certainly McCann is under no illusion that a sharp upturn in fortunes on home turf will be required if a challenge is to be sustained.
"Our away form is probably the best in the league, but that's three on the trot we have lost at home," he lamented.
"If you want to win the league that is not good enough. We have to rectify that although it is hard to pinpoint exactly where the problem lies.
"Teams come here (to East End Park) to possibly the best stadium in the league and enjoy playing here or just sit in and frustrate us. Something has been going wrong and we need to sort that out quickly."
The shoddy performance on Saturday was met with a shower of jeers from the stands as the final whistle sounded. And, although naturally upset by the reaction, McCann insisted that he fully understood where the fans were coming from. "The fans are just as frustrated as we are and want to win just as much as we do," he concluded.
