Eubank Jr beat DeGale by a unanimous decision at the 02 Arena.
The 29-year-old went to the 12th round to claim the vacant IBO super-middleweight title.
This was the same title he lost to George Groves last year.
And footage has emerged from the fight which shows the boxer had some brutal ways of getting his win.
In the clip, Eubank Jr has reached the 11th round against DeGale.
The referee brings the pair together after a brief pause.
Chunky goes in for a punch – but the Brighton-based fighter has something different planned.
Eubank Jr ducks under the 33-year-old’s hits and puts his body into his opponent.
The 29-year-old then lifts DeGale off the ground before slamming him back down.
And the London-based fighter is left stunned as Chris Eubank’s son stands over him.
But DeGale was not the only one blown away by Next Gen’s moves.
“Looks like Eubank Jr will be the new WWE world champion”
Fans on Twitter believed Eubank Jr was ready to take on WWE after his boxing ring antics.
“That was a full on spine buster by Eubank Jr,” one said.
Another commented: “Eubanks Jr auditioning for a future career in WWE.”
While a third made a huge claim about the boxer’s potential in the combat sport.
“Looks like Eubank Jr will be the new WWE world champion,” they said.
And a fourth asked: “WWE are you interested in Eubank Jr?”
But some fans were left disappointed with the bout, branding it a “s*** fight”.
Legendary boxing commentator Mike Costello revealed who Eubank Jr could face next.
And the leader of BBC’s boxing coverage said the 29-year-old has inherited one thing from his father.
While Next Gen made one big change ahead of the IBO super-middleweight title fight.
