Wasps will move top of the Aviva Premiership if they beat Gloucester on Saturday - but rugby director Dai Young expects a tough challenge in the west country.
Young's men are currently second, a point behind leaders Saracens, but lost at Kingsholm last term.
Young said: "I am sure there is going to be lots of talk down there about knocking us over on the weekend - like they did last year - and reigniting their season.
"They have been unlucky in a few games this year, and I think their luck is going to change soon. We are certainly wary of how good a team they are.
"It's up to us to make sure we enforce our game-plan and are accurate if we want to get the win.
"We were on a really good run when we went to Kingsholm last year, but lost the game, and that was probably the one loss in some big games that was the difference between us finishing second or third in the table.
"Gloucester have a huge amount of pace and dangerous players in their back-line, and they have a really strong pack, with a good set-piece.
"Their line speed is also really good, so I am sure they will try to stop us playing and they have a number of players who really like to attack the contact area."
If Wasps triumph, they will be overtaken at the Premiership summit should Saracens defeat Sale Sharks on Sunday.
And while the form guide suggests an away win for Wasps, 10th-placed Gloucester undoubtedly possess enough ability to upset the odds.
Gloucester rugby director David Humphreys said: "Wasps have outstanding players and an outstanding coaching team. The players they've brought in this year have had a huge impact and didn't take long to settle in and performed well right from the start.
"When you look at their team and the depth that they have, despite having some injuries and players away on international duty, they will still come very heavily loaded with quality rugby players.
"They are second in the Premiership, so it will be a huge test for us.
"We've had a couple of weeks of Anglo-Welsh action which has allowed us to look at some of our younger players and give them an opportunity.
"But it has also allowed some of our players who have played a lot of minutes in those first Premiership games an opportunity to rest, recover and get themselves ready for what is going to be a huge run into Christmas."
