Blackburn Rovers manager Paul Lambert believes that his side should have had a penalty against Huddersfield Town, but that any points would have been undeserved.
Town triumphed 2-0 at Ewood Park thanks to another strike from top scorer Nahki Wells, and a second half own goal from Rovers defender Matt Kilgallon.
David Wagner hailed the team display which led to a coveted clean sheet, but his opposite number argued that the game had been decided by two big errors.
"We made two mistakes, incredible mistakes," declared Lambert.
"The thing was we were the architects of our own downfall today," Lambert said. "The first goal was a catalyst of errors. I thought Matty Grimes should have passed it instead of shot. The more sensible route would have been to play in Matty Kilgallon.
"Then Shane, I don't think you can make excuses for. It was a major error which he knows and has held his hands up. I can't be too critical of Shane because he's performed really well for us.
"For the second goal, we have been defending set plays really well but that just summed up the afternoon.
"We huffed and puffed, we had some chances in the second half but we didn't deserve anything from it."
However, Lambert did think that his side should have had a penalty for handball.
It was a third consecutive home defeat for Rovers, who are now below Town in the Championship table.
Added Lambert: "I thought we should have had a penalty but things like that are not going our way."
