3 FROM 4 FA CUP REPLAY PREDICTIONS RIGHT

Newbon predictions: I got three out of four right on Wednesday night! I had Aston Villa to beat Crystal Palace (3-1),Stoke to beat Manchester City (2-1) and Spurs to beat Bolton (4-0).Unbelievably West Bromwich Albion let me down losing 2-1 at home to Reading.Albion were 2-1 going  into stoppage time when Reading equalised and then scored the winner in extra time.How do you account for that?
