There is only one match left for the Blues this season, but still plenty to play for.

A win over the Waratahs at Eden Park on Friday would seal the franchise's best season since 2011 when they were beaten in the semifinals.

The franchise's supporters have suffered through plenty of false hope and disappointment since then, but have every right to feel more optimistic since the arrival of coach Tana Umaga and in particular the Blues' past three performances.

The Blues will take on the Waratahs at 7.35pm Friday.
