The Wales manager, who worked alongside Vincent Kompany at Burnley last season, said the biggest shift in top level football has not been in tactics but in athleticism.
His remarks followed England manager Thomas Tuchel’s claim that long throws and direct play were back in favour in the sport.
“I think the physicality is clear and it has been for a few years,” said Bellamy.
“It has become a running game. It has become beyond extreme with the physical capabilities,”
“We found it with Burnley – we built a Championship team that could come out of small spaces.
“Then, go to the Premier League: cyborgs, that’s what you’re up against.
“It was unreal. They just run you but also have ridiculous ability. That’s why you pay £80m for that type of profile.
“Then you look around the team and see £40m, £50m, £60m [players].”
Tuchel had suggested England should embrace direct methods, arguing “long throws are back.”
But Bellamy insisted the more pressing reality for managers is coping with players who blend pace, endurance and technical quality at an unprecedented level.
His comments came as Wales gear up for consecutive friendlies against Canada – on Tuesday night - and England next month.
Bellamy handpicked the fixtures to push his squad ahead of their crucial World Cup qualifier against Belgium.
“I was like: ‘Give me the toughest,’” he said.
“Look, I’m fully aware I could get beaten and – can I say this? – get my ass kicked but what would I gain from playing a lesser team, where we know where we are?
“This is a tough game. We’ll see where we are. It gives us a good opportunity to be able to get better.”
Canada, now led by Jesse Marsch, will face Wales in Swansea. It will be the first men’s home international at the venue since 2020, and Bellamy is pushing for a packed house.
“I believe national teams, countries like us, should be playing in front of full stadiums,” he said. “I might be pushing it, but I expect that.”

As of Monday, around 15,000 tickets had been sold for the match.
The night will also celebrate Joe Allen’s career.
The former midfielder, who retired from club football in May, will be honoured with a pitchside presentation from Swansea legend Alan Curtis.
Allen, 35, was one of Wales’ most significant figures on the field in the past 20 years.
He first joined Swansea as a nine-year-old in 2000 and went on to make 220 senior appearances across two spells, interrupted by a move to Liverpool in 2012 and a later stint with Stoke City.

For the national team, Allen won 77 caps after debuting in 2009 under John Toshack.
He was central to Chris Coleman’s Euro 2016 semi-finalists, earning a spot in the UEFA Team of the Tournament.
He also featured at Euro 2020 and the 2022 World Cup before initially retiring from international duty in 2023.
But Bellamy persuaded him back, briefly, in October 2024, convinced the veteran still had more to contribute.
That decision highlighted the manager’s desire to blend experience with youth as he shapes a new era for Wales.
