Bluerover
Player Valuation: £50m
Balls debut was August 20 1966 against Fulham away (he did score though)
I had another look at that results site again!! Of course he signed after the World Cup and I misread the blinking page - I was using the phone so print is smaller. Still I knew Ball signed in 66 so I cannot explain not copping the error other than rushing it!@
Anyway it seems it was Fred Pickering (who scored 2) in a 5-2 home win over Northampton. 48,489 on 21 August 65. Temple also got 2 and the GV.
Sorry!!
