Jamie McDonnell is aiming for a late stoppage win over Tomoki Kameda before stepping up a division to face Scott Quigg and Carl Frampton.
The WBA world bantamweight champion defends his title against Japan's Mexico-based Kameda in Corpus Christi, Texas, on September 6 and win or lose says it could be his last at 118 pounds (8 stones, 6 pounds).
McDonnell hopes victory will lead to a showdown with the Dominican Republic's WBA 'super' bantamweight champion Juan Carlos Payano (17-0, 8 KOs) or against fellow Britons Quigg (31-0-2, 23 KOs) and Frampton (21-0, 14 KOs), who hold different versions of the world super-bantamweight title.
"I watched Juan Carlos Payano beat Rau'shee Warren the other week and that fight [against Payano] is the one I want," McDonnell told ESPN.
"If I win this one, there are bigger fights for me and the Payano one is the one I want. If that fight can't be made, or against the WBO kid Pungluang Sor Singyu, I think I will move up a division and it will be time to take on the likes of Scott Quigg, Carl Frampton, Nonito Donaire.
"There are some big pay days at super-bantamweight for me potentially, more money, better kids. I'm big for a bantamweight and the plan was to step up after I beat Kameda last time, but I made the weight the best I made it and the rematch offer came in."
McDonnell (26-2-1, 12 KOs), 29, was floored in the third round but recovered to win a narrow unanimous decision over Kameda (31-1, 19 KOs), 24, in Texas three months ago.
The Doncaster boxer had contemplated making the move up to super-bantamweight after ending former WBO champion Kameda's unbeaten record. But McDonnell decided to take the rematch and believes he will be stronger, technically more refined and better prepared when he meets Kameda again.
"Kameda is going to want it more but we've been working on different things in training camp and I'm punching with more power and rolling into different kinds of shots," McDonnell told ESPN.
"The combinations are coming along easier and I've been working on technique especially in the last few weeks. There will be a lot on the table on his side with it being over there again but I'm confident of beating him again.
"The technique has come on 50 percent and I'm hitting harder so that will play a big factor in the fight. I feel in a good way and peaking just at the right time.
"For the first fight against Kameda I was going into the unknown, fighting in America on a PBC card, but I know what to expect now, I know how it operates. I had lot of distractions last time and we had a six hour drive to get to the venue. We've learnt from that and we're going to be based in Corpus Christi from the start.
"Hopefully I'm more prepared this time and it won't be as close. I'm hoping I can stop him - I want to make a real statement.
"I remember thinking in the last fight when I got back to the corner and asking Dave [Coldwell] what round it was and he said eight and thinking 'Oh no, is there enough rounds left for me to win it?'. This time I need to take it to him from round one with a good pace and if I'm not tagged by stupid shots hopefully I can stop him in the 11th or 12th round.
"I can't let him look busy because he will win on points. I was lucky last time to win the decision over there because there really was nothing in it. I need to make a statement and dust him off because I don't want a third fight."
