Paul Turner admits Newport Gwent Dragons are running scared of Guinness Premiership table-toppers Bath.
Dragons coach Turner saw his men make a flying start in the Heineken Cup before this weekend's daunting trip to the Recreation Ground.
And Turner fears a backlash from the English leaders after Bath's last-gasp 18-16 defeat at three-times champions Toulouse last weekend.
Turner said: "I would like to say I did not watch Bath's performance in Toulouse but I did. I was not surprised by their performance in Toulouse and they should have won. They will take a lot of positives after giving them the runaround.
"In the past Bath played dour rugby but they have moved onto another level now. They have the best attack and are the best team in England.
"Sides who fall off against them and miss tackles are put to the sword so we will have to defend really well and play to our maximum. It will be a huge challenge for us."
The in-form Dragons are full of confidence following four straight wins over Ulster, Edinburgh, Newcastle and their opening 32-22 European triumph against Glasgow Warriors.
But the Welsh region have never won an away Heineken Cup tie across the Severn Bridge in four campaigns.
Now Turner has pin-pointed Bath's potent South African half-back pair as the key to breaking their duck on English soil.
Turner said: "I watched them beat Wasps in Wycombe a couple of weeks ago and they have a fine all-round game. But the key to the way they play comes from their half-backs. "When scrum-half Michael Claassens plays well, Bath play well while Butch James gives them another dimension and is a World Cup winner."
Turner has named the same side with veteran flanker Colin Charvis again included.
Newport Gwent Dragons: P Dollman, G Wyatt, R Sidey, M Stcherbina, R Fussell, J Arlidge, W Evans; A Black, T Willis (capt), R Thomas, A Jones, L Charteris, J Bearman, L Evans, C Charvis
Replacements: L Evans, S Jones, A Coundley, G Webb, A Hall, R Lewis, S Connor, A Smith
As the countdown continues for RWC2015, Tournament Chief Executive Debbie Jevans visited the Millennium Stadium to discuss preparations for the eight matches and reveal the positive news that 100,000 tickets for games at the home of Welsh rugby have sold in the last seven days.
Jason Harries is targeting a first win on the World Series circuit this season with Wales. The series returns to action this weekend in Dubai where Harries is part of a team hoping to build from its efforts in round one in October.
Wales skipper Jevon Groves says his side have addressed a few points from Gold Coast and aim to 'hit the ground running' in the next two rounds of the World Series, kicking off with this weekend in Dubai before heading off to South Africa next week.
Wales Sevens manager Steff Thomas is hopeful his side can build from a quarter-final spot in the opening round of the World Series in Australia when his side take part in the forthcoming double header in Dubai and South Africa.
