Owen Farrell has returned from the World Cup with the hunger to prolong his career for as long as possible.
Farrell led England to a third-place finish in France following an agonising semi-final defeat by South Africa but, unlike a number of his international peer group, the 32-year-old has no intention of looking towards the finishing line.
Ben Youngs, Courtney Lawes and Jonny May played their final Tests at the World Cup, while Dan Cole, Joe Marler, Danny Care and Manu Tuilagi are also close to signing off at the highest level.
But Farrell has raised the possibility that he could still be present for Australia 2027 as England enter a period of rebuilding.
"I love what I do, I'm passionate about it and I don't see that slowing down any time soon," the Saracens captain said at the season launch of the Champions Cup at Tottenham Hotspur Stadium on Wednesday.
"I'm unbelievably lucky to do something that I'm really passionate about and I want to play as long as it can if I'm still excited about what I am doing.
"The two go hand in hand because if you're not excited then you won't do what you want to do anyway, you won't play for the teams that you want to play for and you won't play to the standard that you want to.
"I wouldn't sit down and set targets. But I also wouldn't say they are not in the back of my head, quietly.
"I wouldn't be one to say 'I have written this down, this down and this down, this is what I want to achieve and this is what I am working for every day'. But they are there in the background.
"The exciting bit is what's in front of us. Where you can take what you've been doing and how to get the best out of yourself. Hopefully there's loads more of that."
Farrell's immediate aim is to help Saracens challenge for silverware on two fronts with the Premiership already under way and their Champions Cup opening against the Bulls on December 9.
Saracens have won three European titles, their most recent coming in 2019, and the competition retains a special place in Farrell's heart.
