Pompey are looking to consolidate their playoff spot with another victory this week.
With 58 points from 36 games, Danny Cowley's side are fifth in the table and have won back-to-back encounters under the new manager. Previously, a run of five winless outings saw Kenny Jackett given the boot.
While things are looking on the up for the south coast side, their Manchester counterparts are staring at a drop.
The Dales are rock-bottom in the standings with just seven wins all season. They are five points off safety with just 10 games to go.
They managed to stave off relegation last year by just four points, but do not appear likely to enjoy the same fate again this season.
