Conor Benn will be a very interested observer this Saturday night, when domestic rival Josh Kelly challenges EBU welterweight champion David Avanesyan at SSE Arena in Wembley.
Benn is training for his own scheduled fight on April 10, against veteran Samuel Vargas.
If Benn and Kelly win their respective outings, there is a good possibility that their mutual promoter, Eddie Hearn, will match them in a grudge match.
While Benn is supporting Kelly to win - he fears that Avanesyan might by too much for the Olympian to handle.
Kelly's recent performances have varied from impressive to lackluster.
The outcome, says Benn, could depend on Kelly's tactics in the outing.
"It's a hard fight but I back the Brit," Benn told Sky Sports. "I hope Kelly does the business, I really do.
"Not only for our fights further down the year, but I want to put Britain on the map. But my opinion on the fight? I believe Avanesyan might be too much. I can only go on their last two performances and Avanesyan's were great, [they] were outstanding.
"It's going to be a hard one for Kelly. But if he lives up to the hype and praise that everyone gives him, he'll come through with flying colors and really show what he is made of. He will rise to the occasion. But Avanesyan is an animal. Mid-to-late rounds, Avanesyan stoppage or Kelly will out-box him. It depends how Kelly moves on the night.
"It's now or never for Kelly. He's got a massive amateur pedigree, he's done it all in the amateurs, he's [26 years old]. He needs to make these steps up quickly. I'm at the other end of the spectrum. I'm young with no amateur experience so I've got time. I could have another 10 learning fights but he's got to push on because everyone puts him on a pedestal."
