The survey, conducted by the Daily Mail, had over 100,000 responses from supporters of every Premier League club.
Manchester United's owners, the Glazer family, have come in rock bottom - despite the club signing four of the 17 most expensive players in history. However, the angst from supporters of the Whites' rivals comes from how the club is run and a poor track record of managerial appointments since Sir Alex Ferguson's retirement.
At the other end of the scale, Radrizzani is well liked at Elland Road, having appointed Marcelo Bielsa and helped get the club back into the Premier League after a 16-year absence.
The survey also asked which top-flight owner was 'most damaging to the health of football' with Manchester City's Sheikh Mansour gaining the biggest share of the votes with 32 per cent.
Newcastle United's new owners were second with 18 per cent of the votes while outgoing Chelsea owner Roman Abramovich had a 13 per cent share.
With a huge range of differing opinions, here is how every Premier League club owner is seen by their fanbase, starting with the lowest approval rating...
