Mike Tindall is set to call the midfield tune for Gloucester as they look to book their place in the Heineken Cup quarter-finals with victory over the Ospreys at the Liberty Stadium on Saturday.
Gloucester - the only team left with a 100 per cent record in this season's tournament - will qualify for the last eight with a game to spare if they can do the double over their main Pool 2 rivals.
The West Country giants won 26-18 at Kingsholm in a Round 2 thriller and Tindall expects more of the same on Saturday.
"It will be a big battle for us and I think its going to be exactly the same as it was at Kingsholm," said the England centre.
"It's a massive challenge for us and for them because if the Ospreys don't win they are pretty much out and if we win then that's us at the top of the group and that's us through.
"We want to shut that down now and be able to enjoy the Ulster game and go out there and try and get the top seed.
"Our ambition is to be the best in Europe and it would be nice to go all the way without losing a game, and that's how we look at it. We want to go into those quarter-finals as the top seed.
"In the long run that means a home quarter-final and possibly then the semi-final in your own country - that's where we want to be sitting. But, having this ambition, means putting in the performances.
There were 16,000 people at Kingsholm for the first head-to-head and now maybe as many as 20,000 at the Liberty as Gloucester bid to make it five from five and the Ospreys bid to keep their Euro dream alive.
"That is why you play rugby for these big occasions and it's all about being able to showcase yourself in those situations and that's what we're going to try and do as a team," he said.
"We've started so well it would be devastating if we went and threw it all away by not winning these last two games. We want teams to fear us and that gives you a psychological edge, and, if we can win these last two games, especially away from home in the Liberty, then that lays down a marker."
