.../Q/..::
There has always been home or advantage on every country hosting a cup finals just because they want them to go far abit in the tournament but they may not actually win the final stage because by them things could have been gone tougher than expected, i so much believe that that's just the only way to encourage and compensate the hosts as it may not sound well getting knocked out at the early stage, it's a on rare case seing the host country getting to final or winning the cup.
The best example of his comment and perhaps the eternally remembered one is that of England, the organization of the World Cup in 1966 remains as a reference that when you have good football you can reach the final and being the venue can happen something like a "ghost goal" and win.
