Enigma 478: Football, addition, letters and a twist

In both the football league table and addition sum below, letters have been substituted for digits. Each letter stands or should stand for a different digit (from 0 to 9), and different letters should stand for different digits. And so they do except for the fact that one of the letters is incorrect on one of the occasions on which it appears (if indeed it appears more than once).
The three teams are eventually going to play each other once, or perhaps they have already done so.
Which letter was wrong? What should it be?
Find the scores in the football matches and write the addition sum out with numbers substituted for letters.
