George Groves questioned whether Chris Eubank Jr. will ever become a world-class boxer after he inflicted the second defeat of the 28-year-old’s career on Saturday night.

Groves retained his WBA ‘Super’ super-middleweight title with a unanimous points win in Manchester, booking his place in the final of the World Boxing Super Series in the process.

And while he prepares to face Callum Smith or Jurgen Brahmer in the final, Eubank Jr. is left to reflect on a defeat that could serve as a reality check.

"He dreams big, which is good on him, but tried to fill it out with fairy dust," Groves told Sky Sports.

"There is no substance to anything behind him. Maybe this is the best way to do it, because you'll never really know his limitations, but he's never going to go any further.

"He either should try something else, or perform."

McGuigan has given Eubank Jr. a reality check

Groves and his coach, Shane McGuigan, put together a gameplan prevented Eubank Jr. from unleashing the flurry of frenetic punches that have resulted in him winning 26 of his 28 fights.

And while the bout went the distance, McGuigan knows that his boxer outclassed Eubank Jr. on Saturday night.

We beat them on many, many different levels,” McGuigan said.

“Eubank Jr. looked lost in there tonight. I feel like he needs to go and reassess his career. I believe he’s a middleweight.

“His willingness to come back after being under pressure impressed me, but I think he should go back down to middleweight, get a new team around him - not cowboys - and rebuild.”

Eubank Jr.: 'I'll be back sooner than you think'

Eubank Jr claimed the IBO super middleweight belt 12 months ago and to relinquish it so soon will hurt.

That said, he vowed to learn from his latest defeat in a classy statement on FaceBook.

“Last night was a war. Two fighters putting it all on the line for a shot at glory is what boxing is all about,” the Brighton fighter wrote on Sunday.

“It was close & I feel I was the more aggressive, busier fighter but George was smart & stuck in there to show the heart of a true Champ.

“There’s a lot to learn from this fight I will go away & work on things I know I can do better. Best of luck to George in the final & I’ll be back sooner than you think.”
