An interesting match:
The Hungarian national team during the first half red shirt, white shorts and green socks at all. Second half way through the match, however, exchanged jerseys. Instead of the red and white jersey played on, in which were two red stripes on the chest. This likely was necessary because at that time the television was black and white picture, and disturbing was the Yugoslav team blue jersey, white shorts and red socks.
