Arsenal and Manchester United have already secured their locations in three WSL keys alongside Chelsea, but the place that has not yet been decided will end.
Rene Sligers’ side will feature two games at the BBC at 12:15 at the Emirates Stadium.
The Gunners faced two consecutive defeats in the game in which they scored nine goals, but faced a United club that must climb to jump at the table.
It will determine the final standings for the teams to enter the Champions League next season.
Like the champions, Chelsea automatically deserve the new round of the league, which starts in October with 18 teams to replace the old stages of the group.
Anyone who finished second in the WSL in the final stages of the September qualifiers, while the third team must move to the second round in August.
