Lynn Howells has warned his Celtic Warriors about the danger of complacency if they are to progress to the quarter-finals of the Heineken Cup.
The Warriors travel to northern Italy to face Calvisano on Sunday with qualification from Pool 6 poised between themselves, Perpignan and current table-toppers Wasps.
Bonus points and even try count could prove crucial in deciding who of the three will progress, so the Warriors' remit against the pool's bottom club is quite simple - win and win big.
Unfortunately their fate also lies in the hands of Perpignan doing them a huge favour by beating Wasps, by more than seven points though with few tries for either side.
But no matter what happens some 400 miles away in the south of France, Howells knows only too well that it will count for nothing if his side are frozen out in the Dolomites and fail to collect maximum points on offer in Italy.
Richard Parks and Ceri Sweeney will both probably be fit to play if their recovery from respective injuries is managed correctly this week.
But the biggest concern will be the risk of the Warriors suffering a hang-over from their two sell-out clashes during the past fortnight against Europe's big guns when they step down to face the pool's basement side.
So Howells, a wily and seasoned campaigner in the usual pre-match brinkmanship, must now lift his side one more time to prevent any slip ups.
"We have had some big games against Wasps and Perpignan during the last month but if we tail off in our performances then we will not qualify, it's as simple as that," he said.
"It won't matter what happens in Perpignan, we can't pay any attention to that. All I'm concerned with is Calvisano. People are talking about bonus points but we have got to win the game first."
The Warriors will be well aware of the threat the Italians pose having found themselves 22-20 down at half-time, after leading by 20, in their last meeting at Bridgend.
"I watched them at Wasps last week and for half-an-hour they were 6-0 ahead. So you should never underestimate them, they have some quality players who can cause us problems," said Howells.
"In a competition like the Heineken Cup you can't stop performing. The players know that and it's the message I will be drumming into them. What amazed me was that we managed to get a result against Perpignan last week on the back of a bad set-piece.
"The fact that we won is testimony to the character of the team and they will need that again, but we cannot afford to have another game like that."
Among the players Howells must put his arm around to get the best out of again is lock and forward linchpin Robert Sidoli. The Wales second-row had one of his quieter games against Perpignan and is said to have taken the failings of the Warriors' lineout upon his own shoulders.
"Rob has been a bit down on himself this week as he took the lineout problems that we experienced quit personally," said Howells.
"The good thing is that he has got experienced heads around him who have put their arms around him and assured him it was just one of those games and that it will be fine for the next game. I have assured him that it has got to be right for the next game."
Howells, with the luxury of choosing from a near full-strenth side for the second successive week, has handed Sidoli the chance to redeem himself as well as renewing his calls for Steve Hansen to consider second-row partner Deiniol Jones for Wales.
He said: "The people at national level should be looking at him. The sign of a good player is performing consistently well and I can't think of a game that he hasn't done so for us."
As part of the build-up to next month's Cardiff 2014 Heineken Cup and Amlin Challenge Cup finals weekend, ERC has joined forces with the WRU, Cardiff Blues and adidas to develop an annual grassroots community rugby programme targeting young players.
The Ulster Rugby full back, Jared Payne (No 15), has been suspended for two (2) weeks following an independent Disciplinary Hearing in Dublin arising from the Heineken Cup quarter-final match against Saracens at Ravenhill Stadium on Saturday, 5 April.
