and of course undisputed greatest of all time?

considering the multiple formats today and the amount of games against so many different opponents it is impossible for anyone to average more than 99 in test cricket

the don himself would have averaged lower than that in a professional era

so what would it take for a modern batsman to be considered superior?

60+ average in both tests and odis and a very good (50) average in t20s as well as over 40 centuries in both formats?

or even that would not suffice because his test average would still be 30 points lower??
