LEE McGregor admits he will be back in the gym tomorrow to prepare for Las Vegas after becoming European champion with a devastating knockout of Karim Guerfi on Friday.

The Edinburgh-born bantamweight added the continental crown to his British and Commonwealth belts in only his 10th bout.

McGregor stopped the Frenchman inside the first round after leaving Guerfi floored three times.

The 24-year-old is now expected to fight on the undercard of friend and stablemate Josh Taylor’s super light undisputed bout with Jose Ramirez in America on May 22.

And despite having had no break since he entered camp last September, McGregor has no qualms about returning to training immediately.

“I have a completely different mindset now, a proper professional now," he said. “I’ll have a little celebration but normally in the next couple of weeks I would go away, eat crap and balloon up in weight, have a few drinks and just do stupid stuff.

“I’m not going to do that, I’m loving my life and loving boxing. Monday I’ll be back training. I’ve sacrificed a helluva lot and been training for this since September.

“I would not mind a little break but you can’t turn down opportunity to go over to Vegas and fight on the undercard of your best mate’s undisputed fight, there is no way I wouldn’t do that.

“I can’t wait to get back into camp and push him on because he did that with me. We are always pushing each other on and challenging each other in all the sprints.

“I’ll get my good break after that one, perfect time for the summer everything opening back up.”

A rematch with Kash Farooq could also be on the cards this year but McGregor believes he could soon by competing for world titles.

“Ben Davison is the best trainer in Britain, I can’t get over how much MTK [promoters] have improved me and I’m really excited how good I can be in eight months, I think I could potentially be fighting for a world title in eight months," he said, speaking to IFL TV. "I'm not scared to take on any challenges. I’ll get in there and fight my heart out.”

McGregor, however, admits he would not rush into any fight with "The Monster" Naoya Inoue, the undefeated holder of the WBA and IBF titles.

“He’s the man, he’s the man," he said. "I’m not ready for him yet but the mentality I’ve got, the way I train, the way I’m improving, if he is still there in 12 months and I’m in that position, I’m not going to not fight him.

“That is life changing stuff financially, for my life, everything. I’m not scared to take on any challenge but I’m not stupid at the same time.”
