Edinburgh Rugby stay rooted to the bottom of Pool 1 without a single point after they suffered their fourth straight group defeat when Racing Metro 92 beat them 15-3 at a soggy Murrayfield in their Round 4 contest.
Last year's semi-finalists have not scored a try in 320 minutes of tournament action and all they had to show for their efforts was a Piers Francis penalty goal.
Head coach Michael Bradley said the match had been a "harsh lesson" in game management but that he could still take positives from the performance.
"The effort was fantastic, particularly the pack. When the ball was in play, they made their tackles, carried the ball, and the defence, right across one to 15," Bradley said.
"The boys made their tackles, and there were some great offensive tackles.
"But some of our management of the game, particularly in the early part of the first half, was not good.
"The type of game and conditions it was meant you had to play in the right areas, take your kicks when they came your way and we weren't able to do that, therefore we lost.
"In conditions like that, the key issue is that you play in the right areas. More than that, I think we needed to manage the match better than we did.
"It's a lesson for us really, and a harsh lesson at that.
"We weren't playing for much apart from the fact that we were playing in front of our own fans. We haven't got a point in the tournament so far and we wanted to move that on."
