Munster face off against Scarlets at Thomond Park in their end-of-season finale, the Welsh side also having plenty to play for.
Scarlets are one place above Munster and still harbour hopes of breaking into the top four when all is said and done on Saturday.
And with Ospreys breathing down Munster's neck - they are four points behind in seventh - Foley is urging his troops to finish the season with a bang to ensure they are dining at Europe's top table next season.
"We have to win," said Foley. "We know that. They (the Scarlets) have to win to catch Ulster. Ospreys have to win to catch us and Ulster have to win their game so within those two games there's a lot at stake. It's like a mini-league.
"We're all very conscious of it but we have to keep an eye on Edinburgh as well, so it's important that we get our job done and if we get our job done then well, it's in our hands.
"Rather than looking around for other people to do you a favour it's in our control, it's about us going out now and delivering a performance that can win the game.
"We're in the same boat this week. We need to make sure we win the game this week, otherwise we're reliant on other people not getting results."
