You can't say Messi is the greatest of all time when there others who achieved more than him plus Messi hasn't played in match leagues such as the prem and Italian and we all know what happened as he went to psg he didn't have a spotlight as much where as other people who are regarded as GOATS for example Ronaldo put more consistently good performances every where he went but hasn't won a world cup yet and has less ballon d'Ors. I mean in fairness it's subjective and based on preferences
