It will replace the leagues and it would include every world cup teams from 1930 to 1998.And i mean everything,even teams like Paraguay(1930) or Egypt(1930).Every single world cup team ever.Like i said it will replace all the league.Example,the uruguay world cup 1930 would replace the brazil league,the 1934 and 1990 will be replacing the italian league,basically it will be like a new game all over.
