Adama Traore's 25-yard strike that cannoned off the crossbar and hit Leeds United goalkeeper Illan Meslier on its way back out, found the net in a very unorthodox style.
Both teams looked to have sussed each other out and tactically, had effectively set up to not concede too easily or too early.
• Did both teams choice of formation work yesterday?
Wolves stuck with their usual 3-4-3 formation with their back three turning into a back five when defending. At a glance, it looked like their midfield two of Ruben Neves and Joao Moutinho might get overrun by Leeds' three but they managed the game well as a pair.
Wing-backs Nelson Semedo and Jonny defended well when they were called upon and also got forward to force Leeds back at times. Their involvement was subsequently adequate in Wolves' resolute performance.
The front three of Pedro Neto, Willian Jose and Traore did not work as well as Nuno Espirito Santo would have liked, as they did not combine to cause much threat on the Leeds goal.
Neto was Nuno's biggest threat going forward but Adama and Jose were fairly quiet thanks to some excellent defending and man-marking from Leeds.
All in all their choice of system was effective in yesterdays affair despite a lacklustre attacking output.
Jamie Shackleton played as the holding midfielder and the system looked back to its normal best.
Leeds were able to break the play up very effectively through Shackleton and their build-up play from the back was much better than it was previously against Arsenal.
With Dallas at left-back and not Ezgjan Alioski, at times wide-man Jack Harrison looked isolated because Dallas was more conserved than Alioksi usually is.
Whilst this is not a negative, it meant that Harrison was not as involved as he would have liked but it meant Leeds were much more stubborn defensively.
The attacking players created a number of opportunities and their efforts could have been rewarded when Patrick Bamford stung an excellent finish past Rui Patricio only for it to be narrowly ruled offside.
Leeds United's formation is never the issue in games and Marcelo Bielsa is very unlikely to ever change his set-up. What made the difference in yesterdays game was the players he chose to play his system. That's what made it work.
• Leeds United's positional personnel
Last weekend's loss against the Gunners grew a large base of critics from Leeds fans because of the positions Bielsa chose to play his players.
The absence of midfielder Kalvin Phillips last week saw three positional changes, with Ayling going from right-back to centre-half, Struijk moved into Phillips' role in midfield from centre-half and Shackleton came in at right-back.
This week, Bielsa chose to keep Ayling and Struijk in their normal positions with simply replacing the again absent Phillips with Shackleton.
The decision seemed to work massively in Leeds United's favour because everybody knew what they were doing. Ayling and Struijk were in their normal positions where they have been effective this season and the versatile Shackleton patrolled the midfield well.
Tyler Roberts was the only other new member to the starting XI as he came in for Alioski. Roberts would play in the number 10 midfield role just behind Patrick Bamford which meant Dallas moved to left-back.
The truth behind last nights set-up is that it worked.
It was much more effective than the set-up against Arsenal and Leeds looked a lot more resolute and harder to break down defensively.
The players appeared more settled in their positions and they were able to play their normal fast-flowing passing game.
• Were Wolves told to shoot from distance?
A very common theme to Wolves' attacking play was shooting from distance.
Wide man Neto struck four shots goal-wards yesterday evening, three of them were outside of the box and one of them really tested Meslier in the Leeds goal.
Moutinho struck well over from about 25 yards out and the shot from Traore that resulted in the home sides goal also came from a similar distance.
It almost seemed that a tactical choice of Nuno was to shoot from long range.
Maybe they thought they would test the Leeds goalkeeper's confidence after his mistakes last week against Arsenal or maybe they thought that shooting from range was their best chance of scoring.
Whatever the reasoning behind it, in the end, it did work for Wolves as their goal came from a shot that was outside the penalty area.
Bielsa would have been happy to allow the home side to shoot from distance as it rarely caused them any major problems.
For the majority of the game, Leeds were touch tight with Traore and apart from his shot for the goal they managed to nullify his chances of getting in behind and near the goal.
Ultimately the teams were fairly evenly matched and it either needed a mistake, a bit of quality or a bit of luck to settle it.
