This prompted one reporter to ask Advocaat whether he was worried Sweden would run up a large score against a much smaller Luxembourg side, who had only won one of their previous eight qualification matches.
"But what if Sweden win with like 8-0 against Luxembourg?" asked the reporter.
"They won't win 8-0, what a stupid question that is," Advocaat said. "8-0? Well, no I don't believe that."
Unfortunately for Advocaat, Sweden went on to hand the Luxembourgers with their sixth defeat of the campaign in an 8-0 romp.
Despite the Netherlands' 3-1 win over Belarus a few hours later, Sweden's obliteration of d'Roud Léiwen has made their mission of World Cup qualification virutally impossible.
The two nations face off against each other in Amsterdam on Wednesday morning (NZT), and because of Sweden's improved goal difference of 12, the Dutch need to win by at least seven goals to make the European play-offs.
With the Netherlands, who have finished in the top three at the last two World Cups, almost certainly out of contention to qualify for Russia 2018, Advocaat could try writing off his own team's chances to try and salvage an unlikely win.
