Table schema:
CREATE TABLE table_name_47 (polish_cup INTEGER, ekstraklasa VARCHAR, position VARCHAR, player VARCHAR)

Question: What is the lowest Polish Cup, when Position is "Midfielder", when Player is "Miroslav Radović", and when Ekstraklasa is less than 1?
SQL: SELECT MIN(polish_cup) FROM table_name_47 WHERE position = "midfielder" AND player = "miroslav radović" AND ekstraklasa < 1
