This is shaping up to be the best battle for automatic promotion in the history of the Championship.
The top four are separated by just five points after a Che Adams double inspired Saints to a bruising victory over Preston.
Russell Martin's side still have to travel to Leicester City and face a tantalising final day clash at Leeds with all of the top four on track to achieve 90 points or more.
But it is Martin's men who have the most momentum and, playing like this, they will be a match for anyone.
