I mentioned it before, he turned down the opportunity to have a world title fight and then also moved away from Hearn and his Matchroom Boxing promotions.
Commentators said he needed more fights before he took on the challenge of a world championship belt, they were probably right and from what I saw in his performance against Stepien I think he is not ready yet, he still needs a couple of fights before he fights a champion for their belts.
Buatsi has a lot of belief in his skills and that is why he left Matchroom Boxing and Hearn to go it with another promoter. He felt he was offered a world title fight too early in his career and for that reason refused the fight and subsequently parted ways with Hearn and his promotion company Matchroom Boxing.
But wait there are reports that Buatsi decline to fight Bivol for £1 million and it was revealed by his former promoter Eddie Hearns, there's speculation that he is not ready to fight Bivol.
“We’ve offered him well over £1million to fight Dmitry Bivol, and he turned it down, and that’s disappointing. We want him to fight Callum Smith or Bivol, and he wants to fight Dan Azeez. So we’ll have to see.

A hungry fighter will not turn down a championship because if he wins a title that will double or triple his fighting price and of course his legacy and value as a boxer, there are s many speculations but we'll see who he will fight next and if he'll going to have good matches under his new promotion.
