Dean reports that the team were confident of getting back into the game after the Frenchman's first rasping effort ten minutes before the break, but his searing left foot drive into the top right-hand corner on 55 minutes sparked an onslaught from a confident home side.
"In the first half we played well," he considered afterwards. "In the second they came out, put us under a bit more pressure and we didn't get up the pitch - we seemed to just be defending the edge of the box.
"You can't take the quality of the first two goals away from them. At this level, when a team goes 2-0 up they get a spring in their step and it is difficult to come back into it.
"The second was hard to recover from. We came out for the second half wanting to keep it tight for the first 15 minutes and give ourselves a base - we thought we could get something from the game. When a goal like his second goes in it does take the stuffing out of you a little bit.
"You can defend the first two goals and that is the way you've got to look at it. The third and fourth you can maybe look at a bit differently.
"We've got to get ready for Middlesbrough now and put this to the back of our minds."
Dean Richards says Laurent Robert's second stunner for Newcastle on Saturday proved too much to recover from.
