The home advantage for me can give additional support for the team because with the audience watch the match, each player will have more motivated to win, and they will try so hard to win. But besides the advantage, there will be a disadvantage which is each player sued to play maximally. And there are high tension and stress among the player. And if each player doesn't have a strong mind and heart, they will not perform well.
I was a little confused. You are saying that playing in front of home fans is advantageous and then turned around saying it is also disadvantageous. I guess the motivation to win in front of your own home fans and not let them down is enough to get rid of all the tension and stress. More than stress and tension, playing at home and in front of your very own top cheerers will probably make you more relaxed and comfortable. You are on your comfort zone, after all.
