Leeds United owner Andrea Radrizzani hopes the Premier League will keep Newcastle United in check after their takeover by a Saudi Arabia-backed consortium.
The Magpies are now able to access significant wealth through their Saudi connection, which may lead to big money signings in January and beyond.
Radrizanni, whose Leeds were promoted to the Premier League at the start of last season, hopes Financial Fair Play will not be cast aside as Newcastle look to build up their team.
"Money in football is not always equal to success, it's been shown many times," he told Sky Sports News.
"I think we have a brilliant project run by Marcelo Bielsa and Victor Orta on the football, and we will continue with our strategy to focus on our recruitment and grow our own players.
"This year, for example, we had more than 16 national-team players in our youth teams, and in the last Under 20 England team we had four players on the pitch and two on the bench.
"This is synonymous (with) good investment in the youth and in the academy.
"At the same time, obviously a club like Newcastle or Manchester City - owned and controlled by sovereign funds - they have unlimited possibilities.
"That's why I believe the Premier League should apply fair-play regulation to make sure we play fair, we play in the same competition with similar opportunities."
