London Wasps are bidding to become the first team to win four European club rugby titles - and they are through to the knock-out stages of the Amlin Challenge Cup with a Pool 4 match to spare.
Wasps and Connacht Rugby have both qualified for the quarter-finals in early April with the race for the other three Pool winners honour going all the way down to the wire in Round 6 this weekend.
Wasps - the first team to win both European titles - the Amlin Challenge Cup in 2003 and the Heineken Cup 12 months later - added a second Heineken Cup crown in 2007 and have matched Toulouse with three titles.
And although they have their quarter-final place under lock and key, Director of Rugby Tony Hanks is adamant there will be no let up when they travel to Paris for Thursday night's contest with Racing-Metro 92.
"We are really pleased to have qualified with a game in hand from what proved to be a really tough group and to come out of it after five games has been great," he said.
"However, we are taking Thursday's game very seriously indeed. We want to keep our good run and record in France going as well as getting a good ranking for the quarter-finals.
"And the great thing about getting to this point in the competition is that I believe the Amlin Challenge Cup qualifiers rate themselves alongside a lot of the Heineken Cup teams and you could be better off playing one of the Heineken Cup runners-up who will be joining us than another Amlin Challenge Cup team."
Wasps won the Round 1 encounter 18-13 and although Racing-Metro 92 are set to play their final European match of the season, Hanks expects them to come out with all guns firing.
"They were certainly one of the form French teams just before Christmas, they will be hurting after their last few matches and they will be up for this one in front of their own fans," he said.
"They are a big physical team and no matter who they put out on Thursday you only have to look down their roster to see what great strength in depth they have."
While Wasps and Connacht are home and dry there is one huge head-to-head to decide another quarter-final qualifier among the rest of the five Pool winners.
Bourgoin's trip to Leeds Carnegie will settle Pool 1 - both teams on 19 points - with Bourgoin going for the double after winning their home match 29-19 only to go down on the road at Rugby Parma.
Leeds Carnegie Director of rugby Andy Key said: "You never plan for these things but as the group developed, we became aware that there was always the possibility that it could come down to the last game between ourselves and Bourgoin.
"We're delighted that we've put ourselves in that position and even more pleased that we are playing such an important game at home.
"It promises to be an old-fashioned cup game with the winner progressing to the quarter-finals and we're really looking forward to it.
"It was a job well done by the boys at Parma in Round 5. We knew we needed to try and take maximum points from this game after Bourgoin won in midweek and now this sets things up nicely for Sunday.
"We were careful not to under-estimate Parma as they had already beaten Bourgoin at home. We knew Parma would compete and they scored a smart try at the start of the second half but I thought we controlled most of the game. In the end we were just too strong.
"The most pleasing aspect of the game from our point of view was the performance of several players.
"There were a number of our lads who had not had the chance to play a lot of rugby and a lot of them put their hands up by taking this opportunity.
"Ceiron (Thomas) gave a solid display at fly-half, kicked all his goals and created one try with a real piece of magic so deserved his man of the match award. But there were a number of players who could have won it as well. It has given the coaches a number of tough calls for this weekend, which is exactly what you want."
