Simon Katich was key to Hampshire's double-winning triumph this season - but the Australian will now turn his thoughts to denying the Royals an unprecedented treble.
Katich will play for his native Perth Scorchers in the Twenty20 Champions League and he is set to line up against Hampshire in the group stages.
The Royals need to come through the qualification stages first but Katich is confident they can, given their limited overs successes this season.
Hampshire won the domestic Twenty20 title in Cardiff and then followed that up on Saturday by sealing a dramatic last-ball victory over Warwickshire to take the Clydesdale Bank 40 title at Lord's.
The next stop is South Africa in October.
"They have a very good chance of qualifying, coming off a great season here and then anything is possible," Katich said.
"Perth play Hampshire in the last game before, hopefully, the semi-finals.
"It will be a tricky day. They only know about me but I know all about them so hopefully that works in our favour."
Katich is yet to decide whether he will return to Hampshire next season and if the CB40 final was to be his last game for the Royals, it was a memorable way to bow out.
Jimmy Adams, captain in the absence of the injured Dimitri Mascarenhas, scored 66 and Sean Ervine blasted 57 with Katich adding a quickfire 35 in Hampshire's total of 244-5.
Warwickshire's reply was led by Ian Bell's magnificent 81 and the Bears were favourites heading into the last over, with seven needed to win.
But Kabir Ali, only playing because Danny Briggs was away with the England Twenty20 team, held his nerve to bowl a dot ball with his final delivery when Warwickshire needed just one to win.
The scores finished tied but with the Bears on 244-7, Hampshire won the trophy by virtue of losing fewer wickets.
"It was an amazing finish for the game. There was a period there we thought we weren't going to win it but we got over the line," Katich said.
"Going into the last over they were favourites. To go to the wire on the last ball, you have to hold your nerve. Kabir was magnificent.
"I missed the final in 2005. Having played at Lord's I know how special it is and I always thought it would be nice to play a domestic final here for Hampshire.
"I haven't decided on next year yet. We have spoken about it but I just want to get home and let the dust settle a bit.
"I have a young family so there are things to consider there and I have a few opportunities out of cricket I have to weigh up when the time is right.
"I have thoroughly enjoyed the six months here. They are a great bunch of lads and that has made it a difficult decision to make.
"They have some good times ahead if they keep progressing the way they are."
Warwickshire captain Jim Troughton put Hampshire in, mindful of the fact the last four Lord's finals have been won by the side batting second and their chase was inspired by Bell's 81.
Even when the England batsman fell, Chris Woakes' 24 from 16 balls took Warwickshire to the brink of victory.
Neil Carter, in his final game for the Bears, scored a four from the penultimate ball of the match but he could not get a bat on Kabir Ali's final delivery.
"We thought it was written in the stars for Neil when he went out," said captain Jim Troughton.
"I was backing us in the last over with seven needed and then Carts hit that four. We just needed a run off the last ball and you can't get much closer than that.
"It's pretty hard to swallow. People said to me afterwards it was a great game and I am sure it was for the neutral spectator but to get so close was tough."
