Question: Of all the teams that played as a team away against Caen in the 2010 season, which one has the highest winning percentage?
Evidence: Caen refers to HomeTeam; which one refers to AwayTeam; the highest winning percentage = MAX(DIVIDE(COUNT(FTR = 'A' where HomeTeam = 'Caen', season = '2010')), COUNT(Div where HomeTeam = 'Caen', season = '2010')) as percentage;

SQL:
SELECT AwayTeam FROM matchs WHERE HomeTeam = 'Caen' AND season = 2010 AND FTR = 'A' GROUP BY AwayTeam ORDER BY COUNT(AwayTeam) DESC LIMIT 1
