Couldn´t it actually go in different direction and butterfly the Revolution of ´56 away. Propably with the best soccer-team in the world, life would be bright enough in Hungary that there is no need to die under soviet tanks. Actually the return of the defeated team led to the first violent protest in red Hungary.
There is actually an older thread about this POD, where I said, that this could lead to no hungarian revolution, which could lead to a neutralist goverment comes to power in West Germany in 1957.
