Celtic boss Tony Mowbray took succour from the Parkhead side's first defeat against Dundee United in a decade by claiming there was a "huge gulf in quality and class between the two teams."
A dramatic last-gasp winner from United skipper Darren Dods gave the Tannadice side a 2-1 win - their first victory over Celtic since 1999 - and left Mowbray looking at a depressing run of only two wins in 10 games.
"I felt there was a huge gulf in quality and class between the two teams and yet they scored from two set-plays," said Mowbray.
"Whether they can continue to score from set-plays, I don't know.
"I don't think we got what we deserved from the game but if you don't defend your set-plays properly, then goals are what the game is about.
"But generally, for about 85 minutes, I think it was one-way traffic.
"We totally dominated the football match. The first half wasn't a problem for us. I never felt they could get near our goal.
"I didn't think they could hurt us other than set plays and ultimately they did, which of course, is sore.
"But they didn't create any other chances."
