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.

Snapped up on loan from Liverpool, the Dutch youngster will be hoping to impress his parent club with a spell in the second tier. He snubbed another temporary spell with Preston to join the Hatters on loan.

He was linked with a move away from the club all summer, but eventually ended the speculation by penning a new contract following his participation in Euro 2020 with Wales.

7. CM: Alex Jankewitz
The Southampton starlet was on the brink of breaking into the Saints' side, but he was loaned out to get some valuable, regular first team football under his belt. His dynamism should be a real boost to Luton's midfield.

8. CM: Pelly-Ruddock Mpanzu
He only went and penned a new deal! The Luton stalwart, who has been with the side since their time in the Conference, committed his future to the club, and starts against Boro.
