Nigel Benn has issued a stark warning to Chris Eubank Jr ahead of his and his son Conor's clash at Tottenham Hotspur Stadium on Saturday, telling the 35-year-old that he will reveal some very telling sparring secrets this week.

Eubank Jr (34-3, 25 KOs) and Benn (23-0, 14 KOs) will meet in a middleweight contest in front of 60,000 fans at Spurs this weekend in the main event of Ring Magazine's first ever card in association with SNK Games. The event will air on DAZN PPV.

Benn has spent the last two-and-a-half months in training camp on the island of Majorca in Spain with his father, other extended family and his trainer Tony Sims.

During that time, the 29-year-old sparred notable names such as WBO No. 1 middleweight contender Denzel Bentley and super-middleweight Bruno Surace, who brutally knocked out Jaime Munguia in his last fight.

Benn, who has fought most of his career at welterweight, and weighed 150 pounds for his last fight, also sparred with IBF super-middleweight champion William Scull, who takes on Saul 'Canelo' Alvarez in Riyadh on May 3 for The Ring and undisputed 168-pound titles.

Benn Sr hinted, however, that Scull, an awkward Cuban, has been no match for his son.

"Training camp has been absolutely on fire," Benn Sr told Louis Hart for The Ring at London Luton Airport upon arrival back into the UK for fight week.

"You'll hear me talking about it at the press conference, I'll let you all know. What happens in Vegas stays in Vegas but what happens in Majorca, I'm telling.

"I'm so excited, when you hear what he done to the sparring partners, who are meant to be super-middleweights but they're more like light-heavy, Conor was just on fire, I'll mention the names on Tuesday or Wednesday.

"We're talking about [a] world class, world champion, who's fighting the week after Conor."

The running theory on the competitiveness of the fight between Eubank Jr and Benn is that if the fight goes long, the former will come away victorious, while the latter will have to rely on his success early in the fight.

It's a hunch that Benn Sr subscribes to, noting that Eubank Jr won't be able to deal with the intensity his son will bring in the first third of the fight.

"I'm telling you now," Benn Sr added. "I can't see it going past three or four rounds, I don't even think it'll go that [far].

"Once [Eubank Jr] sees the power and the ferocity...if I tell you what he's been doing to those middleweights and super-middleweights and light-heavies... mate, they had their hands full with my son, he's just an animal.

"One thing I want you to understand is there's no anger involved, just his passion, ferocity, his determination and his will to win, that's my boy."
