Newcastle raised their Champions League heap with the victory over Chelsea thanks to the tactical bamboozle of Eddie Howe.
Howe insisted that the first half was 'electric' on his part when they went into a goal and a man.
Sandro Tonali shot the tone before Nicolas Jackson lost his head and was sent away for the break.
Bruno Guimaraes decided the draw with a 90th minute goal to earn his side three huge points.
Although the score was a modest 2-0, there was enough to show that Newcastle was much superior.
1. Fast sand
Sandro Tonali embodied the high working ethics of Newcastle against the blues.
He showed incredible endurance and pace to cover the ground to press and put pressure on the opposition.
This helped other press from the front and thereby increased the figures in the box.
This was clear in the goal of Tonali after the ball had won the field.
He and Bruno Guimaraes were then able to act as strikers and step into the box and threaten the goal from which the Italian scored.
2. Botman and rob him
Chelsea was up to ten men after Nicolas Jackson was sent away for an elbow on Sven Botman.
The front three of the visitors were against the changed line of defense of Newcastle, which consisted of five players.
The full-backs Jacob Murphy and Tino Livramento were accused of marking Wingers Noni Madueke and Pedro Neto.
While the three Center-Backs Botman, then Burn and Fabian Schar could man for man with Jackson and midfielders Enzo Fernandez and Cole Palmer.
Burn and Schar, in turn, were allowed to go up the field to mark the midfielders, knowing that there would still be a back four behind them.
Botman marked Jackson, and if he were going to go, Burn and Schar would become the two central defenders.
Chelsea couldn't solve it and it was as if the tone had an extra player on the field.
The trigger for the defenders to make their move seemed to be when Chelsea players would put their foot on the ball.
This stopped the player from Enzo Maresca to get a foothold in the game.
3. Break the box
Chelsea played the entire season with a box -midfield and the tone could break it off.
The tactic uses players such as Palmer who can control the ball and then play it wide while sucking the opposition.
Howe's side came in their backs five and put three of the midfielders in the chelsea box.
This would see that people like Guimaraes and Tonali are accompanied by one of Harvey Barnes or Anthony Gordon, making it difficult for the blues to help the ball forward.
And with the back-five so deep, it meant that a longer or more direct ball would be collected by goalkeeper Nick Pope.
The defense was so well connected that it made it almost impossible for Palmer to influence the game.
4. Change that tone
The second half showed how Eddie Howe could respond to the changes of Enzo Maresca.
Nick Pope was called in action a few times to keep the lead off.
Chelsea abolished the box shape and went for a line of three, which meant that they could dominate the possession because Newcastle still had a back five.
How did this change by moving the formation to a four at the back and a more natural 4-2-3-1 form.
Maresca went back by using Moises Caicedo as a midfielder and full-back who saw them return to dominate.
But Howe was able to change the tide again by calling Emil Kraft and Lewis Miley who strengthened midfield and stopped Caicedo.
5. Palmed AF
Newcastle has done an excellent job by squeezing Cole Palmer away from the goal.
They were able to palpate him and keep him at a safe distance.
If he had had a shot, it would probably have been 35 meters and at that time they supported Nick Pope to tackle the effort.
Palmer also suffered from the change in tactics, because he is more limited than some other Chelsea players.
He kept trying to find space in the game, but was often stuck in his own half and was confronted with his own goal.
