This is the wiki page for the cvar
The cvar determines whether goal replays in games and freeplay will be shown from player perspective or outside perspective. It can be changed mid replay to switch views.
To turn on POV replays, open the console and type
If you put 0 instead of 1, it will give you the default outside view.
The cvar can be toggled on and off with the toggle command:
toggle cl_goalreplay_pov 0 1
This can be bound to a key through the user interface or with the bind command:
bind T "toggle cl_goalreplay_pov 0 1"
