objectives

Same bro

The objective is bugged and EA refuse to admit it

I’ve done everything else apart from that objective

It goes like this

The back heel move in game (which by the way the game itself gives ZERO indication of how to perform) has about 5 different animations. 
Only ONE of these counts as a back heel 
Furthermore, because the game decides whether or not the player will actually perform a back heel, you are now left with a move you aren't told how to perform, and have no guarantee of performing even if you find out somehow how to do it, and then have no idea if you have done the right back heel.
Oh, and you only find out if the game has deemed you worthy of a back heel after the game has finished,

EA has been told this multiple times on multiple platforms and has done....absolutely nothing.

I honestly believe that they are just hoping to wait it out until the "challenge" (and I use that word losely because this is just an exercise in annoying its fan base) ends and they can move onto the next grind they offer such as pass the ball 2383839393 times in a row while sitting on a landmine (which they would consider to be "fun")

This is why EA, officially the worst company in the entire world multiple times, continues to lose fans on a daily basis,

Completely agree and it means a large number of people will not be able to complete that objective, the weekly one and the 2 week overarching one. 

So the way to do this is not a simple ground backheel pass its a stupid way to do it but you need a player with inventive basic or + and u need to do a lobbed backheel pass to a player and thats the only way i was able to do it

EA can you please just change the objective to 5 out of 6 asap.  I just played several games where I had several back heels in each game and none counted.

I watched a YT video on it and did it in 6-7 games.

I used Ronaldinho. Inventive is helpful...

The trick tho is to hold L2 and a very quick tap on X and offcourse pass perfectly backwards... If u hold X to long. The player wont do it... Quick tap

"The trick" (again not mentioned AT ALL in the game)
Use this playstyle (again not mentioned AT ALL in game)

My god, how are people thinking "this is a fine"

You have to press l2 left stick back and pass to do a back heel, and the ball has to go backwards otherwise it won’t count
