But Jones knows that success in the international arena doesn't guarantee more of the same on the club scene and that hard work and competition for places will be key if the Ospreys are to progress past Biarritz Olympique, Saracens and Benetton Treviso in Pool 5.
"The Ospreys are fortunate enough to have seven Welsh players, two Samoans and a Canadian coming back from the World Cup," said Jones, who has made 33 Heineken Cup appearances since 2006.
"Samoa went pretty well, Chauncey had a couple of good performances for Canada and we obviously managed to get to the semi-final.
"Hopefully the Samoans can bring a lot to the region. They showed their quality in the performances they gave out in New Zealand. As Sean (head coach Sean Holley) has said, Kahn was probably the standout player in a couple of games for Samoa, so that bodes well.
"But there's a lot of strength in depth in the back row and Rhys Webb has been going well at nine so there's a lot of competition. Hopefully that can bring the best out of them.
"We were pretty pleased with reaching the last four but it's our responsibility to raise the level of performance that the boys here have already achieved in winning six from seven in the league. We're conscious of that and we'll bring that confidence back to the Ospreys."
Jones has dismissed suggestions that the returning Welsh heroes will be tired after their World Cup exploits, with the British & Irish Lions second row insisting he and his international team-mates are feeling good about returning to club rugby with the Ospreys.
The former Celtic Champions currently top their domestic table and will head into continental competition believing they can replicate that form on the big stage.
And rather than allow a lengthy World Cup campaign to slow that fantastic start, Jones feels the enthusiasm already on show at the Ospreys will help him get over the mental disappointment of defeat to France three weeks ago.
"There is a bit of fatigue there but I will worry about that afterwards," added Jones.
"I think the mental stuff is harder to get over than the physical. Your body can heal quicker than your mind.
"Physically I feel pretty good. Mentally, I'm obviously disappointed still. But it's refreshing to see the Ospreys doing so well, knowing that I'm coming back to that environment. Hopefully I can add something back in here."
Jones' first opportunity to feature for his region is likely to come against local rivals the Scarlets this Saturday, before a mouth-watering encounter with Biarritz a week later.
The Basque giants ended the Ospreys' Heineken Cup dream the season before last with a nail-biting victory at the quarter-final stage in what proved to be one of the most entertaining ties of the tournament.
The frustration of that defeat still lingers somewhere in the back of the mind but Jones insists those feelings won't cloud his side's preparations for their European opener.
"The memories are painful but there are positives there as well. It was a painful result but a positive game. We felt we did enough to win that match.
"I don't think it's about revenge. Redemption would probably be a more appropriate word."
