British professional boxer George Groves picked up a well-deserved victory at the Wembley Arena in London on Saturday, outgunning Jamie Cox within four rounds to confirm his place in the World Boxing Super Series super-middleweight semi-final.

A tougher test awaits the Brit in the 2018 showdown in the competition, with Chris Eubank Jr his next rival.

However, it will not be the first time the pair have faced off, though.

Groves gave a detailed account of the experience he had of sparring with Eubank Jr, almost six years ago - when Eubank Jr. was just starting to step into pro boxing - to help Groves prepare for his British super-middleweight title victory over James DeGale in 2011.

Ahead of the highly anticipated bout, the WBA [Super] super-middleweight champion has already started the verbal duel, trying to play on the psyche of his opponent right from the start.

“Eubank doesn't have the boxing brain, he is stepping up big time against me. He's not good enough. I genuinely felt unstoppable against Cox," Groves said, as per The Independent.

“I felt I boxed very well, Eubank could quite possibly be a bit nervous about it.

“But it doesn't matter anyway, at the end of the day the very best Chris Eubank won't beat me.”

Groves admitted that Eubank Jr. was a stark contrast of his father and he actually wuite liked the fact they didn't speak much during their time in camp together.

“The last time we sparred consistently I think was when I boxed [James] DeGale which is about six years ago now,” Groves continued.

“He was my sparring partner, I brought him in, I paid him, I put him up, I looked after him. We didn't talk in the gym, he just came in and worked.

“I quite liked that about him at the time. I wish his dad would follow that, he would come in and chew your ear off for hours on end. But Junior would just come in, go to the back, get changed, jump in and give you the rounds you needed before going.

“The details of sparring, I won't comment on. There is lots of footage, someone might leak it.”

Groves is the top-seeded fighter in the World Series and it was claimed last week he actually requested the officials to place Eubank Jr. on his side of the draw, in order for them to cross paths in the semi-final.

The former British and Commonwealth champion disclosed what transpired between him and Eubank Sr during the draw in Monte Carlo in July.

Groves added: “His dad has always had quite a lot of respect for me. He's been quite kind to me actually.

“In Monte Carlo his dad came out five minutes before we went to the draw, he had the bowtie on, the patent shoes, the Louis Vuitton case under his arm and he said, 'Oh George, you better not beat my son'.

“I thought, 'he's conforming already! He knows'. It was the last thing I thought he would say.

“It is because he got there a bit flustered, he had just jumped off a plane, he hadn't thought about what to say because an hour later we were behind the curtain and he was shrugging his shoulders and saying, 'Do you think the board would give me a licence to go in this tournament'. I said, 'of course not Chris you're far too old'.

“But he is just enjoying himself and living through his son. His son is starting to find his own feet, what comes with that will be its own pressure.”

Eubank Jr secured his spot in the semi-final after an emphatic win over Turkey’s Avni Yildirim in Stuttgart and he was also present at ringside in the Groves v Cox clash on Saturday.

London football club Fulham’s home ground, Craven Cottage and Cardiff’s Principality Stadium are already being touted as potential venues for the event.
