Wolves 2 Crystal Palace 0
Wolves took control of their European destiny and added to Crystal Palace's misery with a routine 2-0 win at Molineux.
Daniel Podence's first goal for the club and Jonny Otto's low strike clinched victory ahead of the Premier League's delayed finale on Sunday.
Three points at Chelsea will seal sixth place and Europa League football next season.
Nuno Espirito Santo's side remain in this year's competition and host Olympiacos on August 6 having drawn 1-1 in Greece in March, with the victors facing a one-off quarter-final against Roma or Sevilla in Germany next month.
But aside from a moment of magic from Joao Moutinho which helped set up Podence Wolves failed to reach their fluid best against Palace.
The Eagles, with Jeff Schlupp missing their best chance, wilted after going behind and Roy Hodgson's side slipped to a seventh straight defeat.
They will equal a club-record losing streak if they are beaten at home by Tottenham on Sunday, with Spurs ready to threaten Wolves' grip on sixth.
It is debatable how much of a part luck and technology has played in Palace's wretched run of losses, which includes just two goals.
Last nigt there was at least a steely resolve from the visitors, now 14th, to remain firm against their hosts, even after losing Mamadou Sakho to injury after 23 minutes.
It helped sluggish and sloppy Wolves were not at the races and the Eagles wasted a fine opening after 27 minutes.
Wilfried Zaha's quick feet found Schlupp but the wideman dragged his shot an inch wide, serving as a reminder why Palace have only scored 30 league goals this term.
Palace were the architects of their own downfall four minutes before the break.
Wolves had been second best but Andros Townsend's loose pass failed to find Zaha and Joao Moutinho punished them. His delicate chip left Palace floundering and Matt Doherty raced onto the pass to cross for Podence to nod in from close range.
The goal hit the Eagles' fragile confidence with Jonny's adding the second thanks to a quick spin and shot midway through the second period.
