Ronaldo has certainly had his fair share or questionable individual award winnings, but if we are going by this season's criteria he should have won last year.
Modric Ballon D'or was a farce last season, similar to how a Van Dijk win would have been this season.
Ronaldo won nothing domestically in 2018 and was poor for a lot of it. Messi completely dominated La Liga.
Ronaldo was a passenger in CL final. Bar one game did nothing at the World Cup.
The Juve and Spain game carried him that year.
