This was the kind of score line that we all feared before the kick-off and it took only 131seconds for the Hatters to impose themselves and extend their 23 game unbeaten run in the Conference.
Unbeaten at home and also unbeaten when they finish the game with 11 players on the pitch, the Hatters gave a tremendous display and on a pitch that has been poor since the live TV match with Barnet.
The first two minutes were pretty good for us,with Rob Ogleby getting the chance to test Mark Tyler, but the keeper was equal to the task and blocked his effort for a corner.
But it wasn’t to last long as we found ourselves a goal behind on just three minutes asthe home side clinically opened our defence with some neat passing and one touch football, that gave Luke Guttridge the chance to pick his spot and coolly curled his effort wide of the diving Andy Coughlin.
On nine minutes they did it again as Andre Grey rode two tackles that should have cleared the danger, recovered the ball and calmly slotted the ball wide of the exposed Coughlin.
The Hatters did it again on 17 minutes, as a quick one-two between Guttridge and Benson saw the former race through the Wrexham back line and fire passed the exposed Coughlin.
Another chance for Wrexham as Hunt fired over a cross and running in on goal was Ormerod, but he had to stretch to make contact and his effort sailed high over the bar.
Joe Clarke was then unlucky with a cross that drifted and clipped the home crossbar and Ogleby chased a through ball that Tyler was forced from his line to take at the feet of the Wrexham striker.
A Wrexham free kick was headed down by Tomassen in the Luton box, but Hunt’s first time effort spun off his boot and wide.
Six minutes before half time and a poor clearing header by the defence went sideways allowing a cross back into the middle for centre forward Paul Benson to slot home from six yards.
In the seconds before the break, Joe Clarke tried his luck from distance but it drifted high of the target.
The second period started at a slightly lower pace from the Hatters, although they were still able to get some telling crosses in, mainly from their left wing.
A booking for Hunt on 59 minutes, as he tripped Mpanzu in the centre circle.
Luton caused more problems from a corner on 63 minutes, when Ogleby initially headed away, but then Griffiths tried his luck before an overhead effort from Gray was well wide.
The home side made the first sub a minute later as former Wrexham target John Shaw replaced the tall figure of Benson at centre forward.
Then it was our turn with Joe Anyinsah replacing Dean Keates.
On 69 minutes, Howell went to ground with Carrington running behind him down the side of the box and the referee point to the spot, with the former Wales U21 international getting up to send Carrington the wrong way from 12 yards.
With that Andy Bishop was sent on for Ogleby and Luton replaced goal machine Gray with Alex Lawless.
As we moved into added time, Clarke hit a long ranged effort that forced Tyler into a rare save.
The relentlessness that manager John Still has instilled in his team means they just never give up and even in the dying minutes and five goals to the good, his players were still snapping at the heels of the Wrexham players when they lost the ball.
Luton are a credit to the division and have set the bar very high for another team to try and match – as yet few have been able to live with them.
