Gloucester’s Heineken Cup hopes were left in tatters after they crashed to a dour defeat at the hands of Edinburgh at Kingsholm.
Nigel Davies’ men put themselves in a commanding position in Pool Six with an impressive victory over the Scots at Murrayfield last week.
But they failed to complete what could have been a decisive double as their European hopes slipped in frustrating fashion.
Davies said: “Obviously it’s a huge setback for us in Europe.
“We are very frustrated we couldn’t back that performance up last week.
“We didn’t manage the game at all, the conditions dictated that we had to play a certain way and we got it wrong, badly wrong.
“Our discipline let us down again and it fed Edinburgh. They played the conditions better than us, and when you put everything together, that is where they won the game.
“They had a pretty focused game-plan and they stuck to it, and we have got to be able to adapt to top teams who eke out wins.
“It is a mental thing, we were buoyed by last week, but we are still not in a rhythm, we are not in a groove of winning games.
“And you’ve got to do that and eke out wins however you can. We played for the large parts, the wrong game.
“In terms of Europe, all is not lost, obviously it’s a huge setback for us but Munster here is a big fixture for us, and we go to Perpignan, and that might be an opportunity.”
They appeared on course for a victory when the Cherry and Whites pack asserted their authority by powering over for a penalty try but the boot of Jack Cuthbert kept Edinburgh’s noses in front at the break.
Burns nudged Gloucester into the lead early in the second-half but Ben Atiga crossed for a vital try.
And the Cherry and White’s inaccuracy and lack of direction coupled with Edinburgh’s bloody determination ensured the Scots hung on to break the home side’s heart.
Last week’s 23-12 victory over the Scots had kept Gloucester’s hopes of qualification alive but they were once again facing a must win clash following Munster’s heroics in Perpignan.
The Irish province struck in injury-time to snatch a dramatic victory at Stade Aime Giral and move six points clear in the group on Saturday.
And following Gloucester failure to maintain the pressure, they must now triumph in their remaining games against the Heineken Cup giants.
Davies made just one change to the side that triumphed at Murrayfield with Tavis Knoyle starting at scrum-half at the expense of former All Black Jimmy Cowan. New-signing Sila Puafisi also lined up on the bench.
Gloucester imposed themselves from the off-set at Kingsholm but were unable to turn their early pressure into points.
They were punished by the boot of Cuthbert, who struck on nine minutes after Knoyle was penalised for taking an Edinburgh player out off the ball.
Burns had the opportunity to level the scores but was off-target in blustery conditions and Cuthbert stretched the visitors’ lead to 6-0 with a monstrous 49-metre effort albeit with the help of the crossbar.
Gloucester continued to dominate territorially and Billy Twelvetrees almost unlocked the Edinburgh defence with a delightful grubber-kick but Martyn Thomas was beat by the touchline.
But that was a rare bright spot as Gloucester wasted any potential attacking opportunities.
They were limited attack and short of ideas as Edinburgh spoiled the ball, soaked up any pressure and snatched precious penalties at the breakdown.
The Cherry and Whites were dealt a blow on 25 minutes when Burns departed to the blood-bin and Edinburgh enjoyed a rare venture deep into the Gloucester half.
But momentum was lost as Ross Ford spilled possession and Gloucester soon grabbed the opening try.
With the hosts’ struggling to unlock the Edinburgh defence in attack they turned to route one.
The pack has received plenty of criticism this season but after fronting up in Scotland they once again flexed their muscle on their own patch.
From a driving lineout they steamrolled through the heart of the Scots’ pack, leaving Romain Poite with no choice but to award a penalty try.
Burns, back on following treatment for a cut to the head, converted from in front of the sticks but Cuthbert once again hit-back to bring the scores to 9-7 at the interval.
Matt Kvesic set the tone for the second-half after bursting through the midfield to set Edinburgh alarm bells ringing.
The break laid the foundations for a try but typically of the previous 40 minutes Edinburgh turned over possession and the opportunity was lost.
Alan Solomon’s men raised the tempo in the second-half and quickly demonstrated exactly how to turn pressure into points.
A Tom Brown break down the left put the Scots on the front foot and following several pick and goes the ball was spread to Atiga, who stepped inside a furious Jonny May to stretch over.
Cuthbert was once again on target but blew his 100 per cent ratio on 57 minutes, as the scores remained 16-10.
And Edinburgh were dealt a further blow with Willem Nel paid the price for an under-pressure scrum with a yellow card on the hour mark.
The Scots were soon fortunate to remain at 14-men as breaks from Tinall and Rob Cook led to a frantic period of play in which Greig Tonks was penalised for a deliberate knock on.
But again Gloucester’s inaccuracy proved costly as they squandered a succession of opportunities and they were dealt a major blow when Sione Kalamafoni was stretchered off following extensive treatment.
They still had field position to push for an all-important try but shot themselves in the foot when Burns was penalised for his over exuberance when trying to retrieve the ball for a five-metre lineout.
From there out Edinburgh kept the Cherry and Whites pinned back to their own half and following a comical Cuthbert miss from the tee, after Ben Morgan was sent to the sin-bin, they pressed for a try of their own.
The Scots went through a succession of phases and Nel appeared to have powered over but lost the ball forward to keep Gloucester’s faintest of hopes alive.
But they were quickly quashed as Edinburgh ran down the clock to gain revenge for last week’s result at Murrayfield.
