The two teams achieved promotion in very different ways. While Chris Wilder's relentless team romped to the title by 13 points, Keith Curle's Cobblers sealed their return to the third tier thanks to a brace of remarkable play-off victories.
But the two sides have their similarities too, not least the unity and togetherness displayed during difficult times, and they are also both laced with quality all over the pitch.
That makes for some tricky decisions when combining the two, although a lot depends on the formation you want to go with. To keep things simple, we've stuck with a straightforward 4-4-2.
Here's who makes our team...
9. Left midfield: Nicky Adams

10. Striker: Callum Morton
Half a season on loan wouldn't ordinarily get you into a team like this but Morton is no ordinary loan player. Made an incredible impact, firing the Cobblers to promotion with 8 goals in 12 games, including three in the play-offs.

12. Unlucky to miss out
David Cornell, Jordan Turnbull and Scott Wharton were all unfortunate to miss out at the back, while Joel Byrom, Ryan Watson, Sam Hoskins and Vadaine Oliver can also feel aggrieved not to make the team. Photo: Pete Norton
