25 is still a superb average anyway, so the difference doesn't really matter at all. The problem with such stats is that, ironically, you might have rated Imran higher if he had performed slightly worse at home. Say he averaged 22 at home and 25 away.. a difference of 3 is hardly worth pointing out. The fact that he did so brilliantly at home somehow seems to work against him
If his home average was say 18-19, and away he averaged 30+, you would have a point. Here, it's just irrelevant because he was obviously very good away as well. The fact that he was absolutely godlike in home conditions isn't a negative
