James DeGale says he wants to unify the super middleweight division ahead of his bout with Rogelio 'Porky' Medina on Saturday.

The IBF super middleweight champion warned Badou Jack and Lucian Bute, who fight on the same card in Washington DC, that he is "coming for the winner" but seemed especially interested in a bout with WBC champion Jack.

DeGale said: "Fight time is here, I'm feeling good, feeling fresh. I've trained extremely hard.

"Porky Medina is a good fighter in his own right, a very good fighter, but there are levels to professional boxing and I feel as though I am levels above him.

"On Saturday night I am going to show you a real performance. My last two performances have gone the distance, this time it won't.

"Best of luck to Badou Jack and Lucian Bute, that's a great top of the bill, trust me, but I am coming for the winner. I want to unify the division."

DeGale later revealed that he had taken the opportunity to remind Jack of his intentions while posing for pictures and said he is relishing his time in America.

When asked if he had spoken to Jack, DeGale added: "I said you're next. That green belt is coming over very, very soon.

"I want a new fresh name on my record. He [Jack] seems like he is growing as a champion, he is getting confident, he wears his shades, he thinks he's the man but when he gets in the ring with me I've got no question that I will beat him. He's got to get past Lucian Bute first so we'll see.

"I remember years ago my grandad, he has passed away now, God rest his soul, but I remember when I was little he said 'they are going to love you in America' and it feels like everything is coming true, it is great."

Medina's last four wins all came from knockout within the first three rounds but DeGale said he does not see a real threat coming from the 27-year-old.

"The quality of opponents he has been fighting have been little geezers in Mexico and that's no disrespect to him, he has got a good win on his record and that's J'Leon Love where he knocked him out and Love was undefeated, very good skilful fighter but there are levels to boxing," he said.

"I feel as though I come from good pedigree, I won my world title on the road and willing to defend it on the road so this guy isn't going to stop my progression."
