Leeds won 3-0 at Reading and Sunderland 2-0 at Charlton. Sunderland is 3 points ahead and has to travel away to Aston Villa and Cardiff, while Leeds has to play Cardiff home and away.
Sunderland has also a favorable goal difference of +30 while Leeds has +22. Leeds and Sunderland should both beat Cardiff IMO, so the Villa v Sunderland game might be decisive with a win virtually guaranteeing the title.
Both sides just dominated the League this season and it is certainly a shame that no promotion to the WSL in 2013 is available for those teams.
