Swansea City moved up to second in the Championship as Conor Hourihane's early goal earned them a smash-and-grab 1-0 win at Kenilworth Road.
Luton dominated for much of the match and missed several chances with Swansea having to work hard to grind out a win.
Hourihane's goal after a decisive break came from one of only two Swansea efforts on target in a game where they were nearly always on the back foot.
Jordan Clark headed wide with Luton's best chance of a frustrating contest.
Andre Ayew, who has been the best player for the Jack Army enjoyed the full minutes of the game.
