Boxing fans expecting to see a ruthlessly aggressive Chris Eubank Jr in his upcoming grudge match with Conor Benn will be rudely shocked, according to one of the latter's chief sparring partners Denzel Bentley.

Eubank Jr (34-3, 25 KOs) and Benn (23-0, 14 KOs) are set to clash in a money-spinning middleweight contest at Tottenham Hotspur Stadium on April 26, over three decades on from their fathers' famous middleweight and super-middleweight title fights.

The build-up so far has been fractious. Insults, threats, accusations and eggs have all been thrown in each other's direction, and the fight, which will be promoted by The Ring in association with SNK Games, Matchroom and Boxxer, is now just under a month away.

Eubank Jr has elected to base his training camp at Churchill's Boxing Gym in South London, while Benn has been preparing in a warmer climate out in Majorca, Spain.

Benn, moving up in weight to fight at 160 pounds for the first time in his career, is said to be used to sparring bigger men, and has been opposite light-heavyweight stablemate Craig Richards on numerous occasions over the years.

For this camp, current British and European middleweight champion Bentley (21-3-1, 17 KOs) has been brought in to replicate the physicality and size Eubank Jr will bring on fight night.

Bentley spent two weeks on the Balearic Island with Benn and his trainer Tony Sims.

Because of Eubank Jr's larger frame, most observers have picked him to beat Benn, who has not had a fight at world level throughout his career so far.

Peacock Gym's Bentley, however, doesn't believe Eubank Jr will centre his game plan on the explosiveness he showed as a burgeoning contender 10 years ago.

Bentley told The Ring: "Eubank ain't the same fighter that he's been. He's still good but he ain't the same explosive, aggressive, ferocious Eubank that we all kind of knew.

"The Eubank that knocked out [Avni] Yildirim with loads of shots, the Eubank that put up a great effort against George Groves or whoever else. In that Groves fight he was relentless even though he lost. The intensity was crazy. Groves was just obviously a smarter boxer and a bigger puncher and naturally heavier.

"Those efforts from Eubank and those fights I just mentioned or even his British title fight against Nick Blackwell, the amount of punches he threw, the relentlessness.

"We haven't seen him perform like that in his last three or four fights.

"As he's getting older I think it will be harder to tap back into that type of version of himself. So he's opted to be a little bit more of a boxer, a bit more clean, fend it around, throw a jab and every now and then turn it up but he never keeps it at that intensity any more."

Asked to highlight what Bentley saw from Benn in sparring that could trouble Eubank Jr, it was intensity, a trait the 28-year-old has shown plenty of in many of his fights.

"He's really intense," Bentley added. "He's going to bring it every second of every round. He's going to be on you. He's full of body punches.

"His body shots are really effective. I think that's what he'll be looking for. Where Eubank's a bit tall on the body he'll probably be an easier target for Connor to hit and he'll be ripping them shots around there.

"That's what Conor's going to do. Conor's going to keep the intensity high, drag Eubank Jr into a fight. Not that he can't have a fight because he can have a fight but try to drag him into a fight and have the fight at his pace."
