So it's OK to count points totals starting in 1992 but not ok to count home form?"Home record"? So what? Since when did we start splitting home and away records off from each other? Oh yeah, I remember, since it was declared open season on Martinez.
Only two stats that count and ones that will stand up long after he leaves:
Best PL points total
3rd best win % of any Everton manager
They^^^^ are stats that the new man with far more cash to spend needs to surpass very quickly indeed....or they'll be out quicker than RM.
