London Welsh assistant coach Gordon Ross admitted his side underperformed in the 38-7 Premiership defeat at Newcastle Falcons on Sunday.
Any hopes London Welsh may have had of kick-starting a survival battle were swiftly banished the Falcons scored six tries - and had the try-scoring bonus point wrapped up by half-time - as they registered their biggest Aviva Premiership win for eight years.
Three of those four tries came in a seven-minute spell and effectively ended any hopes London Welsh may have had of sparking a fightback.
"It's a big disappointment," Ross said after the match.
"Perhaps the most frustrating thing is that we didn't make Newcastle work too hard for their tries.
"We were pretty soft at times in defence and we kept turning over possession and giving them field position and from that they scored pretty easily.
"When you're four tries down after half and hour, you know you're pretty much up against it. There were a couple of positive aspect in our attacking play but we didn't retain possession enough and made it easy for Newcastle.
"The conditions weren't easy but that's no sort of excuse. Any time you lose you're disappointed but we did lose our urgency and dropped off the game a bit.
"It's a massive gap between us and Newcastle and London Irish now but we just have to keep improving. We played quite well last week against Harlequins and were very competitive, but today was a backward step.
"It's tough times for us. The guys trained well during the week and we were expecting a good performance but we didn't step up to the plate and we were well off the pace.
"Newcastle scored two or three nice tries but we weren't competitive enough and didn't make them work hard enough for their scores."
It is difficult to see how London Welsh will make up the 20-point gap between themselves and Newcastle and London Irish, who also won today,especially in the Falcons case as they are playing with some purpose.
"I thought we were pretty accurate today," Newcastle director of rugby Dean Richards.
"We played with the wind in the first half and got four tries and leaked one - which was disappointing - although it was well-executed by them and then in second half played into a howling gale but the boys were pretty sharp actually and the accuracy of the kicking was pretty good.
"We started out probably being a bit too ambitious in the line-out but once we sorted it out and settled down it went pretty well and the lads chose the right options.
"We have players like Sinoti Sinoti, Juan Pablo Socino and Tom Catterick who will challenge sides with the ball in hand and then we have Chris Harris and Alex Tuilagi who can come off the bench.
"We have a back line which challenges any defence and that's why we're scoring tries.
"I don't have any particular number in mind in the Premiership we just go out and try to win every game and where you finish you finish.
"I never look at relegation. Perhaps I should have done last year - but I always look up and you have to challenge yourself."
