The Hatters are expecting to see a fair few comings and goings over the next couple of months, and are already being linked with a host of top quality talent ahead of the transfer window opening later this week.
For a bit of fun, we've fired up the latest edition of Football Manager, and simulated the game to the first day of next season to see how Peterborough United line up with their predicted new signings.
This is how the starting XI and substitutes Luton Town have been predicted to pick in a home clash at Kenilworth Road against Middlesbrough.
13. Sub 2: Ryan Shotton

14. Sub 3: Dan Potts

15. Sub 4: Fred Onyedinma
Onyedinma suffered a knock in pre-season, but is fit enough to start on the bench on the opening day of the campaign. His pace and dazzling dribbling could be a real threat for the Hatters going forward. Photo: Justin Setterfield
16. Sub 5: Sylvester Jasper
Luton went big on the loan deals, and added the Fulham youngster as a last minute addition to their side. He's a rapid winger with bags of flair and a lovely first touch. Photo: Charlotte Tattersall
