The super-middleweight contender fights Andre Dirrell for the vacant IBF title on May 23 in Boston in the United States while Groves is aiming to secure a shot at Dirrell’s younger brother Anthony, the WBC champion.
And DeGale is already looking ahead to bigger and better things should he return from America with the belt ??? and a rematch with Groves could finally be on the agenda.
He told Sky Sports: ???Once you???ve won the title it???s about building and unifying, and being in those great, exciting fights. That???s what I plan to do, but first I need to get past Dirrell which is a hard, hard task in itself.
???I???m confident in doing that and after, it will get bigger and bigger.
???Groves is a possibility but he???s got his own path, he???ll be boxing for the WBC title at the end of the year. So that???s a massive fight ??? imagine unifying titles with two English fighters.???
DeGale???s only defeat in 20 professional bouts was against long-time rival Groves for the British and Commonwealth titles in May 2011.
And although that defeat initially irked DeGale, he believes his reputation has soared beyond Groves??? ahead of a possible second bout.
He said: ???After that defeat, for a year, it did bother me that I???ve got a loss on my record to him. But you move on ??? I???ve had 10 fights since then, won the European title, boxed top 10 contenders, and now I???m boxing for the world title.
???I???ve come on a whole heap, and achieved a whole heap so he???s not constantly on my mind, but it???s a big fight for British boxing.
???I was on a different channel and boxing at shopping centres and he gave me a lot of stick. It???s weird how things change. Now I???m on Sky, boxing for a world title, topping my own bill in America and making good money.
???The roles have reversed. Last time, I was the villain but people are starting to find out about George Groves.???
