A red card, ten men, Mark Hudson up front and a deserved equaliser from the boot of Nahki Wells all added up to a dramatic night at Milton Keynes for David Wagner's men.

The game finished 1-1 after Wells cancelled out Alex Revell's first half strike with just a few minutes remaining on the clock to make it three games unbeaten.

Here's five things we learned from the game...

Philip Billing is an unlucky man

Sky Bet Championship - MK Dons (1) v Huddersfield Town (1) - Philip Billing sent off.

Where else to start but the red card, the evening’s biggest talking point and the moment that defined this Tuesday night clash.

Referee Michael Bull had been quick to reach for his whistle throughout the first half, and it was a shame to see a match between two sides who like to play football and get the ball on the floor stunted somewhat by the constant stopping and starting.

Billing was given his marching orders a mere three minutes after entering the fray as a half time sub, for what Bull deemed an unnecessarily high boot when challenging for the ball on the halfway line.

Replays show that there was no malicious intent, and the midfielder was sretching to win back the ball after a poor first touch - standing at a height of 6ft5 in his socks, Billing’s foot naturally goes a little higher than most.

That red was the third that Bull has shown in his last five games as the main official.

David Wagner confirmed afterwards that Town intend to appeal the decision - time will tell whether they are successful, but the young Dane can consider himself very unfortunate.

His development and contribution in recent weeks has been magnificent, and both the player and club cannot allow this to affect his confidence.

Town have learnt from the Reading debacle

As soon as the card was shown, Town fans could be forgiven for harking back to the last red card - Jonathan Hogg’s in the FA Cup replay against Reading.

On that occasion, Wagner’s men were two goals to the good and had something to defend, but ended up losing 5-2 - even if the score was distorted somewhat by the fact it was a cup game and Town were throwing every man forward in search of a leveller in the closing stages.

Here, they found themselves a goal and a man down on 48 minutes and the mountain grew before collective eyes.

However, Wagner warned after Reading that his team would be better next time and so it proved. They were defensively solid, worked together as a unit and only broke forward when clear opportunities arose, ensuring they were not often left exposed at the back.

Such an approach meant the margin remained a single goal, and it left the hosts restless - both on the field and in the stands - and with a striker of the calibre of Nahki Wells around, Town only needed one chance to snatch a share of the spoils.

Goal just reward for Wagner’s tactics

Sky Bet Championship - MK Dons (1) v Huddersfield Town (1) - Nahki Wells equalises for Town.

If David Wagner’s footballing philosophy reflects possession, gegenpressing and a “full throttle” approach, many would find it hard to reconcile that with two tall centre backs being pushed up front to chase a goal.

Yet against MK Dons, that’s exactly what Town did following the introduction of Joel Lynch after 80 minutes.

It was actually a tactical masterstroke, putting intense pressure on the home side’s back line and leaving them panicking with only a single goal lead, which was eradicated by Nahki Wells, set up by defender and skipper Mark Hudson with a flick a forward would be proud of.

It highlighted Wagner’s fondess for change when something isn’t working or when he sees an opportunity to exploit - he isn’t overly rigid in his approach and isn’t afraid to tweak.

But it also reflected his unwillingness to settle. A goal down and playing with ten men for over 40 minutes, most would have predicted Town to lose.

Not David Wagner. His positivity has permeated every pore of Huddersfield Town this season, and it was in evidence again in Milton Keynes.

He and his team thoroughly deserved that equaliser.

Town were simply not good enough first half

Sky Bet Championship - MK Dons v Huddersfield Town - James Husband claims he's been brought down by Dean Bowditch.

While it was a fantastic point in the end, Town missed a chance to make it three league wins in a row for the first time since December 2013.

While the referee’s decision undoubtedly affected the game as a spectacle, Town’s first half display also deserves some close attention, because it was just not good enough and not what fans have come to expect under David Wagner.

The team didn’t really get going in the first period, and created little of note in the final third despite another improved display from Karim Matmour, who appears to be adapting to the English game.

MK Dons made the early running and it was no real surprise to see them take the lead through Alex Revell, although the nature of the goal and the defending will not have pleased the Head Coach.

It was the worst 45 minutes under Wagner in some time (Brentford springs to mind) - the German said afterwards that he believed it was one of the worst halves of his tenure and the normal “fighting zone” was reduced to a “jogging zone”.

It was a fair point and his two changes at half time showed his feelings. But the front four have played a lot of football in recent weeks. Is this squad too small to play full throttle twice in a week?

Elvis Manu deserves to start against Ipswich

Sky Bet Championship - MK Dons (1) v Huddersfield Town (1) - Elvis Manu.

After helping to change the game at Wolves at the weekend as a second half sub, January loan signing Elvis Manu had to make do with another place on the bench against MK Dons.

Brought on at the break, his powerful running and direct style was a prickly thorn in the side of the hosts’ back line and his fresh legs were a welcome boon for the ten men of Town.

However, as well as his bursts forward, his willingness to track back was impossible to miss.

One particular moment stood out, when the men in white strode ominously forward only to find Manu charging back to rob the ball inside the penalty area, take it all the way back to the halfway line and win a free kick for good measure.

It’s easy to see why David Wagner likes the Dutch winger and moved to bring him in for the rest of the season.

Now he has had time to adjust to the team and the system, it’s time to give some tired legs a rest and see what Manu can do from the start against Ipswich.
