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’s low strike clinched victory ahead of the Premier League’s delayed finale on Sunday.
Three points at Chelsea would 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.
The goal hit the Eagles’ fragile confidence and, as Wolves slowly improved, they began to create chances.
Raul Jimenez’s shot deflected over and Adama Traore linked with Podence 14 minutes after the beak but was denied by Vicente Guaita.
Traore was becoming more of a threat and he contributed to Wolves’ second goal which wrapped up the game after 68 minutes.
The winger bulldozed his way past James McArthur and Tyrick Mitchell and, when Jimenez’s miscued shot fell to Jonny, the wing-back turned and fired in low from 12 yards.
