Manchester City retained top spot by beating St. Polten in their penultimate group game on Thursday night.
Captain Alex Greenwood was stretchered off in the first half before Lily Murphy opened the scoring in the second half.
Barcelona defeated Hammarby 3-0 to join Manchester City in the quarter-finals, ending the Swedish team’s hopes of advancing.
On December 18, Spain will have a decisive battle to see who tops the group.
If Barcelona defeats Manchester City, the two sides will lock in 15 points, so the top spot will be determined based on the head-to-head record between the two sides.
This means that City, who beat Barcelona 2-0 earlier this season and are three points ahead of their opponents, will be top of the table if they win, draw or just one goal apart.
