Kell Brook produced a masterclass at the Manchester Arena last month, stopping his bitter rival Amir Khan in the sixth round.
It had been a fight in the making for over 17 years, but Brook dominated proceedings and showed superior timing and power which Khan had no answer to.
The 35-year-old Sheffield fighter looked reborn and admitted afterwards "my mojo is back".
Brook immediately switched his attention to a battle of Britain with Eubank Jr, a fighter three years his junior. But also a fighter that Brook says he has a dislike for.
"I don't like Eubank. If the fight is right I will fight - I'm a prize fighter," he said after demolishing Khan.
It's a feeling that is mutual, because Eubank Jr, who was ringside in Manchester, is no fan of Brook, but he did suggest a summer dust-up between the pair.
And Boxxer promoter Shalom says he is working hard on a fight for Brook in June or July.
"He (Brook) wants to fight in June or July," Shalom told Sky Sports News. "It's going to be a big fight. We're going to work it out.
"I think Eubank wants the Kell Brook fight. We'll sit down with Kell, work out the weight, work out if we can get there and work out if it's right for Kell Brook.
"Chris also potentially has a world title opportunity that could come in June-July. So both of them have options and I expect to get to the bottom of it in the next week or so."
A Brook vs Eubank Jr clash would no doubt have to take place at a catchweight.
Brook's win over Khan took place at 149lbs - two pounds over the welterweight limit. Brook has fought for the majority of his career at welterweight and became the IBF welterweight champion with a famous win over Shawn Porter in 2014.
He stepped up two weight divisions in 2016 to fight Gennady Golovkin at middleweight. But he was punished in savage fashion by GGG and sustained a fractured eye socket, which led to his corner throwing the towel in.
Eubank Jr has done all his winning at middleweight, the last of which was a comprehensive 12-round win on points over Liam Williams at the start of February.
Just how much weight Eubank Jr would be prepared to drop will prove to be key to the fight happening.
Eubank Jr has said he would "maybe" agree to fight at 158lbs, but no lower. He weighed in at 160lbs for the unanimous points win over Williams.
"You fought GGG at 160 so you will do the same with me if you want the biggest payday (& beating) of your career," Eubank tweeted last month.
As for Brook, well he responded with: "155 otherwise don't mention my name."
