Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Question ###
What is the highest Goals Against, when Points is greater than 25, when Club is "SD Indautxu", and when Position is greater than 3?

SELECT MAX(goals_against) FROM table_name_21 WHERE points > 25 AND club = "sd indautxu" AND position > 3
