I know say Dem go see you for here

EbukaHades10:
No be like that.

I just say make I dey for u in this "trying" time.

A305:
I have also thought about it until I figured the answer in physics.

2 reasons:


1 - The law of inertial: whatever that is set in motion, stays in motion except the force of acceleration is applied to it to give the object more momentum.

When the ball is already in motion from the cross, it's in motion already and so nodding it gives it more acceleration to a new direction of a low/higher trajectory.

Even the best of all keepers can NEVER be in two places at a time because that's the only way to figure out the direction and catch the ball (but what about the new momentum), Still not possible even if two keepers are in that post.

This is why John Terry is still well respected for nodding out that ball against Barca.


2 - Speed calculation: A keeper always calculate/estimate the intensity of speed a ball travels for him to decide to either catch or punch the ball away. This is why many keepers are good at catching and parrying straight shots aimed at the post. But when you nod a ball, the keeper lacks the capacity to calculate the speed of how it started and to what direction it's headed.

This is also the reason wingers attackers like Messi, Ronaldo, Sallah etc scores some thrilling goals with shot from the wing side. The keeper often lacks the ability to calculate because the ball creates a curved motion instead of straight line.

BanevsJoker:

And relatively closer to the keeper, meaning a much shorter time for the keeper to react.

..
Ur explanation make sense..

And most headers come very close to the gk.

fergie001:

1 - 0...you dey lead

EbukaHades10:
Lead where. U wey don overtake since. Abi no be u make us dey "discover crude oil"?

fergie001:

I am not satisfied.......na Jota I go deal with...bet

EbukaHades10:
Jota na anointed and u know what they say about anointed and all.

Atk1nson:
@Op , in addition to what others may have said, a typical corner or free-kick is contended by many players seeking to nod it, it is often difficult for the keeper to figure out who will eventually get the header, creating a lot of uncertainty as to the direction, potential scorer and even his positioning.
