blinking head before start of a game

Hello!

In choice of tactics before a game, when u press and hold on a player his head will start blinking, u can only do this on one player, then under the match he will have something white blinking over his head. (like a little square)

What does this mean?

It is just for coach to better view of player, it doesnt change anything in gameplay/skill.

bloody hell, i forgot you can do that
useful to keep an eye on a new signing in career mode
or to help prevent a semi injured player getting another tackle

Thx for the answer Now its time for a local offline event in Sweden!
