James DeGale turns up late for his pre-fight media conference but issues promise to be prompt in defeating Rogelio Medina

James DeGale arrived three quarters of an hour late for his head-to-head media conference with Saturday night's challenger for his world super-middleweight title, through no fault of his own.

The promoters forgot to send the car to collect him from the hotel where he staying away from the rest of fighters on the card in the DC Armory.

DeGale was gratified to arrive in time to hear Leonard Ellerbe, the chief executive of Mayweather Promotions, pay him this highest of compliments: 'What I like about James is that he reminds me of the great and now retired Floyd Mayweather. He talks a lot of trash, but like Floyd he backs it up.'

Chunky then promised to be extremely prompt when it comes to defeating a Mexican called Porky.

Of Rogelio Medina, DeGale says: 'He's a good fighter but I am some levels above him. My last two fights have gone the distance but not this one. I will knock him out in three or four rounds.'

Medina countered: 'Beware, I am the hungriest of the four men here who are fighting for world titles because I am the youngest.'

The other two are Las Vegas-based Swede Badou Jack, who won the WBC super-middleweight belt by beating George Groves, and Canadian-based Romanian Lucian Bute, a former world champion who is mounting a spirited comeback after defeats by Carl Froch and DeGale.

The two winners of this double header are expected to meet in a championship unification bout later this year.
