Alfa, you will need load of heal kits though and beware of low energy level.
I have been caught several times with low energy and the own goal tactics when a G vs G challenge is on.
by the time i changed my own goal tactics back to a normal one.. i was already 2 to 3 goals down..

but i reckon it is worth the risk as it gives me something like +14 to +20 training points on average a day( depending on the player training speed)...
and if you work that out.. it is something like +10 to +14 attributes for a player in a season.

Good luck doing the training games buddy

That much! It is worth trying, indeed! Thanks!

Like in life, even if you are experienced, you can learn something new everyday. Just keep your eyes and ears open.

Yep but what I don't get is you must have a very daft amount of players to do that with because you'd physically run out of energy you couldn't play that many in a day without draining your energy to 0%
