Ivan Cavaleiro scored the only goal of the game as Fulham departed with all three points on what was a frustrating afternoon at the KCOM Stadium.
“It was a scruffy game between two teams that didn’t play to anywhere near their best,” said McCann.
“Fulham probably started brighter than us and we were slow in our tempo and in our build-up play. We were better in the second half and, if it had finished as a draw, I think both teams would have been happy to walk away with that.
“Fulham taking the lead meant we had to go a bit gung-ho in the second half to try and nick a goal but, in the end, a moment of quality from them has won them the game.
“There was no rhythm in the game. It was stop-start and we couldn’t get going, certainly in the first half anyway.
“I think they’ve had one, or maybe two shots on target. We didn’t have many either, but the difference was a tremendous goal from Cavaleiro.
“The real frustration is it’s back-to-back defeats at home for us. We’re probably the seventh or eighth best team at home, but that is not good enough when you want to finish in the top six. We need to try and find a bit more consistency at home.
“We just have to keep going. There’s 19 games left so still a long way to go. This group has shown all season that it can respond to set-backs and we’re going to have to show that again now.”
