Cardiff City bounced back to winning ways in emphatic fashion on Saturday afternoon, routing Luton Town 4-0 in the Welsh capital.

It was a welcome display from the Welsh club, following a string of poor performances, and Neil Harris will hope that it is just the start of a big turnaround this term.

Here are the talking points from the win over the Hatters.

Sparky the bright spark

When Mark Harris' name was written on the Bluebirds team sheet, there was a mixture of excitement and trepidation.

It was exciting in that Neil Harris had entrusted an academy product to lead the line alongside Kieffer Moore, but a tension owing to an untried, untested youngster starting such an important game in the context of the season and the manager's tenure.

But from the very off, the 21-year-old they call 'Sparky' was bright, energetic and his body was clearly coursing with adrenaline and a desire to impress.

The manager said back in September that Harris offers that little something different, a striker who runs off the shoulder and stretches the opposition defence, and that is exactly what he brought against Luton.

His striker's instincts to make clever runs into the channels and anticipate flick-ons from his towering strike partner Moore wreaked havoc all afternoon and City's forward players reaped the benefits.

Vincent Tan's vision for the club is to up the Welsh contingent, providing a far greater proportion of Wales' squad than they have done in recent years. Well, on Saturday, Cardiff started with four Welshmen - Harris, Moore, Harry Wilson and Will Vaulks.

A statistic I came across on Twitter also informed me that the last time two Welshmen scored in the same game for Cardiff City was May 4, 2008, when goals from Paul Parry and Joe Ledley contributed to a 3-0 win over Barnsley.

Moore and Harris corrected that statistic against Luton.

There are things young Harris has to learn, of course, he made the odd wrong decision, notably when he attempted to capitalise on Simon Sluga's slip and opted for the shot rather than sliding in Moore for an easy tap-in, and sometimes attempted the spectacular when the simple option was the best.

But who can blame him? He was brimming with confidence after his early goal.

On the whole, you cannot knock his performance at all. His youthful exuberance, unjaded by the start of the campaign, was like fresh air and long may that continue.

A penny for Robert Glatzel's thoughts, too, given he came for a hefty price tag just over a year ago and is yet to truly settle, as he watched on from the bench. He has been searching for some form this season and with City tyro Harris now in the fray, his job just got a little more difficult.

Have Cardiff found their goalscorer?

Kieffer Moore has been largely excellent for club and country this season and Saturday's outing was no different.

As the clock ticked on in the second half with the game at 2-0, it was a wonderment that he had not found himself on the scoresheet.

He took up so many good positions, won everything he went for and struck up a great partnership with compatriot Harris.

While the service into him has not always been good enough this term, he has looked Cardiff's most likely scorer in the majority of matches and it was just a matter of time against the Hatters, really.

He latched on to another pinpoint Harry Wilson corner and powered home his header from close range before celebrating animatedly. You can tell just how much it means to him when he scores.

He has now netted five times for the Bluebirds this season - given they have played nowhere near their best for the most part that is quite an impressive haul.

The Bluebirds have been crying out for a goalscorer up front for years and Moore looks like that missing piece of the puzzle which has finally been slotted into place.

The Wales international could conceivably go on to net 15 or more goals this term, perhaps as many as 20, and for a team gunning for promotion that is an absolute necessity.

The above point might help, too, with Harris potentially stretching defences and creating more gaps for him to score, but Moore's contributions and performances this season have been at a consistently high level and when the team really begins to click, you have to feel it will only serve to benefit him further.

Early goals and attacking intent

The main thing which has really crippled the Bluebirds this season has been conceding the first goal, usually preceding the opposition then sitting back and parking the proverbial bus.

Because Cardiff are rarely being taken to the cleaners, it is usually just one goal in it, tightly fought contests in which they have been unable to unlock defences after going behind early.

Neil Harris has spoken about getting that "first goal mentality" for some weeks now and the Luton performance shows just how much of a difference that can make.

Sean Morrison's fifth-minute opener from the set piece, followed by Mark Harris' coolly-taken strike just four minutes after, put Cardiff in the driving seat early on and it is a position they have been in so rarely this season.

It prompted Luton to throw more bodies forward, which in turn opened up so much room for Cardiff's quick wingers and the spritely Harris to exploit.

Leandro Bacuna, too, was excellent and he also really stretched the defence when he bombed forward.

It was great to see Will Vaulks back in the middle of the park as well, adding that bite and energy and he really did turn out a top display. Alongside Joe Ralls, that midfield looked busy and bustling, flanked by wide men who were keen to get forward into spaces which were being manufactured by Cardiff's slicker passing.

A combination of those crucial early goals and a more attacking set-up came together in a perfect alchemy to really punish Luton on Saturday and the visitors had no answer.

The Bluebirds were finally ruthless and went for the jugular from the start for a change.

It paid off to no end. That has to be the blueprint now going forward.

It was an 'embarrassment', says Welshman Jones

It is always worth keeping an eye on the opposition manager's quotes after the game and Rhondda-born Nathan Jones was scathing in his assessment of his team.

Cardiff players have been on the receiving end of some tongue-lashings this season, but in the Bluebirds' defence they haven't been dismantled like Luton were on Saturday.

And Jones branded his team's display at Cardiff City Stadium an "embarrassment" after City's scintillating display.

"I’m embarrassed if I’m being honest," Jones said. "Because of the level of performance. Regardless of what we wanted to do and how we wanted to start we went 2-0 after nine minutes.

"The goals we gave away were a real embarrassment and we have to be better than that because it has been a bit of a theme at times, it was the same away at Millwall, identical.

"When you go 2-0 down after nine minutes in the Championship, it’s very hard to chase a game. If you’re Bournemouth or Norwich maybe you can do that with a £70million budget, but we’re not in a position where we can chase that kind of lead down.

"It wasn’t a good day at the office, it was our third game in a week, we had low energy and we didn’t play well and we got punished for it.

"I wish I had made 11 changes, I genuinely do and we have to address that.

"We seem unable to handle three games in a week and keep this high levels so I’m going to have to make changes and freshen things up to get the level of performance.

"We don’t get tuned over in midweek, it always seems to be in that third game and the nature of the goals were embarrassing.

"Every time they put the ball in our box they looked dangerous."

Not out of the woods just yet

While Cardiff fans are well within their rights to have enjoyed watching that display on Saturday, this is just the beginning of the road.

That performance against Luton now has to be the norm, not the anomaly.

That is now four wins in 14 games and that ratio has to dramatically improve in the build-up to Christmas if City are to be within touching distance of those top spots.

It's certainly a start and we have seen just how good this Cardiff team can be, they certainly have the players to do it, but it means nothing if Cardiff, for whatever reason, default to their old ways against Huddersfield and beyond.

There are always going to be selection dilemmas and needs must when it comes to players' fitness amid a gruelling schedule, but the team against Luton looked to have struck a much better perfect balance than we have seen under Neil Harris this season.

That will be encouraging for Harris and the City fans.

One win doesn't undo months of underwhelming displays, though, the management will also know that.

This cannot be a false dawn like the Barnsley game, a 3-0 win which was followed by more dire displays.

it must represent a turning point in this season.

This squad, on paper, is comfortably top-six. Some might even think it to be a top-two squad, but they have not shown themselves to be promotion candidates up until this point.

But, if those silly errors continue to be eradicated and this attacking intent, full of verve and with a clear direction, can be replicated consistently, then there is no reason the Bluebirds cannot turn this poor start around.
