Someone of your age and experience knows only too well that it's easier to score goals later on, especially when you bring on good players against tired defenders, so I'm surprised you've contributed this load of drivel. Glatzel and Ward have done so well as substitutes for this reason.
Glatzel has started 19 league games this season. We've won 5. He's scored 3 when he's started a league game. He's scored 3 in 6 games when he's been a substitute.
Ward has started 7 league games this season. We've won 1. He's scored once when he's started a league game. He's scored 4 in 16 games when he's been a substitute.
Paterson has started 17 league games this season. We've won 9. He's scored 4 goals when he's started a league game. He's scored once in 15 games when he's been a substitute.
