The Oranje dominated the first half at the PGE Narodowy in Warsaw and went in at the break 1-0 up thanks to Gakpo's close-range finish after 13 minutes.

Poland threatened an equaliser at the start of the second period, but Bergwijn sealed all three points on the hour mark with a composed finish.

The result means Louis van Gaal's side just need to avoid defeat in their final group game against Belgium on Monday to progress to the Finals next June.

The Netherlands lost Teun Koopmeiners to injury inside the opening five minutes, but they went ahead when Gakpo applied the finishing touch inside the six-yard box following a flowing move that cut through Poland's backline with ease. 

Memphis Depay squandered a golden opportunity to double the visitors' advantage, blazing over from a tight angle when a simple pass to Gakpo would surely have resulted in a goal, while Steven Berghuis curled narrowly wide. 

Poland was much brighter after the interval and twice went close to an equaliser through Arkadiusz Milik and Sebastian Szymanski. 

Its hopes of getting back into the game were ended in the 60th minute, though, when Bergwijn coolly slotted past Wojciech Szczesny after being teed up by Vincent Janssen.
