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.

### Tables ###
TABLE: CREATE TABLE country ( Country_name VARCHAR, Country_id VARCHAR )
TABLE: CREATE TABLE match_season ( Country VARCHAR, Position VARCHAR )

### Question ###
What are the names of countries that have both players with position forward and players with position defender?

### Accurate SQL ###

SELECT T1.Country_name FROM country AS T1 JOIN match_season AS T2 ON T1.Country_id = T2.Country WHERE T2.Position = "Forward" INTERSECT SELECT T1.Country_name FROM country AS T1 JOIN match_season AS T2 ON T1.Country_id = T2.Country WHERE T2.Position = "Defender"
