Poland picked up three points to put themselves in pole position to progress to the Round of 16 ahead of the final game of the group phase.
Saudi Arabia played well but goals from Zielinski and Lewandowski made the difference, ultimately, as did Al Dawsari’s failure to convert his penalty. Juventus keeper, Szczęsny saved his penalty and the follow up shot.
It was otherwise a competent performance from them.
Poland are unbeaten in their opening two games of a World Cup tournament for the first time since 1986 (also W1 D1). In the process, they have equalled their longest run of consecutive clean sheets at the World Cup, keeping three in a row for the first time since 1978.
Saudi Arabia have lost each of their last nine World Cup matches against European teams dating back to 1994, while failing to score a single goal across the last eight.
