David Humphreys has admitted that Gloucester Rugby made too many mistakes in their defeat to Northampton Saints in the Aviva Premiership.
The team's director of rugby told BBC Sport: "Coming here it's always going to be a set-piece game, but those conditions meant that it was going to be a case of whichever team made the fewest mistakes, was able to control field position and didn't give away penalties.
"I thought for long periods of the game we did control field position, but we made too many mistakes and obviously gave away too many penalties with a kicker of the quality of Stephen Myler on the pitch.
"Scrummaging's not just about one player, it's about the whole eight - you've got to give credit to Northampton, it's what they've built their success around over the course of the last few years - a very strong set piece."
The result leaves Gloucester 10th in the table, while Northampton jumped up to fifth.
