If you're going to compare statistics the only way you can do it is by the percentage of goals that each player scored in their league.
Dixie's 60 season 1927/28 saw 1765 goals.
Therefore he got 3.39% of that total.
Messi's current La Liga total of 29 in 2010/11 has seen 837 goals.
Therefore he has 3.46% of the total.
Incredibly close statistics and you'd have to say Messi is doing very well.
However I'm struggling to see how any Evertonian can disparage Dixie, of all players, with such ridiculous comments. It's one thing saying Messi is doing as well as or better than Dixie, but to start claiming it was miles better is just baffling.
