After a 10-month season split in half by the winter World Cup in Qatar, the Premier League, Bundesliga, Eredivisie, Primeira Liga, Scottish Premiership and Women's Super League all come to an end this weekend, and there is plenty still to be decided.
Two relegation places remain unfilled in the Premier League, the Portuguese title race has unexpectedly gone down to the final day between two bitter rivals, while in Germany pretty much everything is still up for grabs with the title to be decided and four teams still in danger of relegation.
On top of that, titles and relegations could also be confirmed with a game to spare in France and Italy.
Here, Sports Mole runs through the permutations for all of this weekend's action from around the top leagues in Europe.
FRIDAY, MAY 26
LIGUE 1
Le Havre will be promoted to Ligue 1 if they win away to Bastia, or if Metz fail to win away to Sochaux.

Schalke will be relegated if they lose. They will also be relegated if they draw and Bochum avoid defeat, barring a 23-goal Stuttgart defeat too. Schalke will also be relegated if they, Bochum and Stuttgart all win and Augsburg record anything other than a defeat which, coupled with Schalke's win, sees a 15-goal swing in goal difference.
