Henry, at 29, would easily have his pace & acceleration at 20 each. But its at around 17 or 18 at the start of the game in FM08. Suprising to see them go up at his age. But maybe Barca just put him on a heavy aerobic schedule. As per the game, the stats dont start dropping before the player completes 31 years of age. But SI has screwed his stats up big time anyway. The worst being what they've given him in the finishing & composure areas.
As for the goals to games ratio, have to say its quite silly. Maybe he just had a couple of games where he scored like 6-7 goals in each of them or something?
