Question: Which country had the game that Away team made the most goals?
Evidence: the most goals refer to MAX(FTAG), which is a short name for Final-time Away-team Goals;

SQL:
SELECT T2.country FROM matchs AS T1 INNER JOIN divisions AS T2 ON T1.Div = T2.division GROUP BY T2.country ORDER BY SUM(T1.FTAG) DESC LIMIT 1
