1open fifa world
2.open trainer
3.add goals to home side
4.skip half time (press F4 once to activate, and then press it again to disable it)
5.start second half, pause the game, and wait for ~5 minutes
6.unpause, press F4 twice again and there you go you won without playing, and also no connection loss
