The rule itself is as clear as day.
"Any goal scored or created with the use of the hand or arm will be disallowed this season, even if it is accidental," says the Premier League.
Jesus' goal, technically, was created by the use of Laporte's arm, regardless of whether there was any intent.
The rule was changed after some high-profile goals were scored by the accidental use of a hand last season.
To give three Premier League examples:
Last August, Willy Boly scored for Wolves against Manchester City after the ball touched his arm.Alexandre Lacazette handled in the build-up to Pierre-Emerick Aubameyang's goal for Arsenal at Crystal Palace in October Sergio Aguero used his hand in scoring his third for Manchester City against Arsenal in February
