Light-heavyweight Buatsi proved his power in claiming a bronze medal over the summer, whilst Joyce was the subject of a controversial decision to Tony Yoka in the super-heavyweight final.
Both medallists are being linked with lucrative moves to top promoters next year, whilst Fowler says Buatsi and Joyce have all the tools necessary to take the paid ranks by storm in the coming years.
“Josh has lots of talent and I know because I’ve sparred him loads in the past,” Fowler exclusively told World Boxing News.
“He’s one of the only people who can take my shots and still come forward. He’s got a great chin and I think he can go all the way in the pros.
“For Joe, he won the gold medal, I say that because, in my mind, he did. He should have been given the decision against Tony Yoka and I couldn’t believe it when it went the other way.
“Yoka’s fight before should have seen him go out and someone else should have been fighting Joe but he got that decision in that one too.”
On 29 year-old Joyce mixing it with the best heavyweights in the world, Fowler added: “He has a few things to work on but the raw talent is there and as he showed at the Olympics he can be a handful for anyone.
“Despite coming home with a silver, I have no doubt Joe can be better for it in the future.
“We saw with Anthony Joshua how far you can go after the Olympics and who knows, we might see Joshua v Joe Joyce for the world heavyweight title one day – which would be great,” he said.
