First of all thanks programmers for this brilliant idea which brought life back to top 11.
I think World cup should become a standard competition not just a temporary tournament.
I think it should be held out 1 time only every year to keep its charm and prestigiousness.
There should be a QUALIFICATION among the managers of same nationality so only the best one can represent his country.
I suggest that the qualification should be be held on three stages ( every 4 months).
A- stage 1 : September ( local qualification) all managers of same nationality compete and only 1 can represent his country
B- stage 2 : December ( Continental qualification to chose 24 national teams from 4 continents ( Asia- Europe- America - Africa )
C- stage 3 : April ( official qualification to 12 National team from the 24 from every continent )
D- stage 4 : July (world cup to determine the best manager / national team in the world.
My 2nd suggestion is to allow friendly matches not be only against 7 bot countries but against real managers from all over the world
3- to allow fans to support you during world cup games.
4- improve the training system to become like the normal training.
5- allow managers to play the 2nd version of world cup with same players that play regular competitions ( thus purchasing suggested players and investing rests can be encouraging and worthy.
