Will Spencer admits the performance from the Leicester Tigers in Saturday's defeat by Bristol in Round 9 of the Gallagher Premiership "let down" Geordan Murphy and the coaching staff.
Speaking after the full-time whistle, Spencer said: "We’ve let Geordie and the coaching staff down because that’s not up to the standard of how they prepare us during the week and the effort they put in.
"It was a good week, we were confident and it was great having the international lads back, but all that means nothing if you don’t show up and perform."
Spencer was one of the standouts for the team in a game to forget, running for 84 metres from 20 carries and beating seven defenders, as well as making two line-breaks and missing just one tackle in an 80-minute effort in the pack.
"We need to right the wrongs of today and so far this season."Will Spencer speaks after the loss to Bristol
Spencer said the squad were devastated and the scenes in the changing room at Ashton Gate was "one of the worst" he'd ever experienced, acknowledging that the group had allowed their heads to dip after decisions went against them early on in the match.
"That changing room was one of the worst I have been in after a game of rugby, everybody is devastated," said Spencer.
"We felt sorry for ourselves when decisions or moments went against us, which we can’t afford to let happen, we can’t let our heads slip."
Tigers now face back-to-back European fixtures against Racing 92 and Spencer says he is relishing the chance to "right the wrongs" of recent weeks against last season's Champions Cup finalists.
"I would play tomorrow if I had the chance, because of how disappointed I am," he said.
"We know they’re a big team, but when we get things right - and we haven’t enough this season - we can beat anybody.
"We need to right the wrongs of today and so far this season, we need that next game as quick as we can."
Leicester Tigers travel to Paris to face Racing 92 in Round 3 of the Heineken Champions Cup on Sunday (4.15pm local time) before welcoming the French club to Welford Road in the return fixture on Sunday, December 16 at 1.00pm in Round 4.
