In Everton's 139 year history (either with or without three points for a win - which came in 1981) Martinez's 72 point season has been passed three times only: by Kendall in 84/85, 85/86, 86/87...but even here that was with 4 extra games in a season (42 games as opposed to 38). And no one else has achieved winning 21 games in one season since the games were reduced down from 42 to 38.
21 wins and 72 points from 38 games. I'm sorry, but just recognise the effort, appreciate it and move on to denigrating his other two seasons if need be. But be respectful of a historic effort by both players and manager that season.
As stated before: it will be a long te to wait before that tally is approached, never mind bettered.
