How often is my opponents formation updated?

Hi Guys,

I am able to see my opponents formation by clicking on his name and seeing "squad" but how often is that updated?
I assume it's the formation used in a previous game? But unsure.

EDIT: I do mean outside of a LIVE game situation. This is all planning for the next match

Thanks for the help :)

It's updated whenever a change to the team is made. However if this change occurs while you are playing the game, then you won't be able to see the change until you refresh

Seems silly to me that it 's updated all the time but Thank you!
