James DeGale says he would only consider a rematch with George Groves if he takes the lion's share of the purse.
Groves lost out on the WBC super-middleweight crown at the weekend after losing in a split decision to Badou Jack.
IBF champion DeGale watched the fight, and couldn't resist having a dig at his old rival on Twitter – particularly after Groves rejected the offer of a summer match-up with him earlier in the year.
The two fighters ended up on seperate paths to world title shots instead, and while DeGale successfully claimed the IBF belt after sending Andre Dirrell to the canvas, Groves was not as successful.
"Wrong move, wrong move," he told Ringside Reaction. "Every dog has his day. Funny how things work out.
Asked if he would offer Groves a world title shot, DeGale said: "As I said, I'm in boxing for the big fights and if the British public want it and demand it, let's do it.
"But we'll have to negotiate the purse. Maybe 90 [per cent for me]… 10 per cent to him. We'll see."
On Twitter, DeGale was even cheekier, posting several laughing icons aimed at Groves, adding: "Looks like Wembley's gone tits up next year. Congrats @BadouJack … Ready when you are!"
Commenting on the message, DeGale added: "I got a bit of stick for that tweet. Remember when I was boxing at Bluewater and the stick he used to give me?
"But he's got to ask himself some questions. Can he mix it at the top level with the elite fighters? I don't think he can."
