The defeat was Town's third in a row as they sit fourth bottom in the Championship at the halfway point of the season. To see how the Hatters rated on the day, read below.
9. Luke Berry: 7.5
Fourth successive start for Berry as he got on the ball when possible, trying to find a killer pass through the Swans defence when the chance arose.
10. Harry Cornick: 7
As against Preston, had a real opportunity to put Town in front late on, but after rounding Woodman, lacked the conviction to go for goal, opting to find Moncur. Couldn't make the most of his other openings either.
11. James Collins: 7
Good link up play when Luton got the ball forward and almost set up Shinnie with an inviting cross from the right. Early booking meant he had to be extra careful afterwards to avoid an early bath.
12. George Moncur (SUB): 6.5
Had a few bursts forward, but couldnt quite beat the covering defenders on the line after Cornick had rounded Woodman.
