Australia paceman Peter Siddle admits he is enjoying being Kevin Pietersen's nemesis in the Ashes series.
Siddle has now dismissed the England batsman 10 times in total after having him caught by Mitchell Johnson during the tourists' first innings of the third Test in Perth.
Pietersen's departure for 19 proved to be a pivotal moment and cemented Australia's dominance as they completed another emphatic victory to take an unassailable 3-0 lead in the series.
"He's obviously inflicted a lot of pain on us over the years, so to see the back of him is always nice," said Siddle.
"To be the one to get him, it does bring a lot of joy to myself personally, but also the team.
"It just comes down to the challenge - you want to challenge yourself against the best players in the world and he's one of those.
"I rise to the challenge and try to build as much pressure on him as I can. I'm lucky enough to get him, but it could be anyone in the side."
Siddle has been on the losing side in his three previous Ashes series so he is relishing finally being part of a winning team.
"It's been a long time coming for a fair few of us," added the 29-year-old. "To have played in three and lost, obviously there was a lot riding on this series.
"Growing up, I never really saw an Australian side lose an Ashes series. So to be a part of a few myself had been disappointing and it was unfinished business."
