Second, geographical location. I have been playing football in this land, and I am familiar with everything, whether it is the climate or the grassland, which is a big advantage compared with strange guests.
Third, I have to say the referee. The referee always takes care of the home team, at least I think so occasionally when I watch the ball.
Fourth, it should be a psychological problem. Because it is my own home, I feel that I am the boss, and because I lost at home, I will be sorry for the audience, so I forced myself to win.
