Funny you should say that when immediately I think of Maradona on Argentina and their great success, even if he was covered by 3 or more players Maradona found a way to be invaluable and sometimes score directly despite all the blocking and cover the opposing team would give an obvious star like that.
I take the point though because for sure its true of team games not even not just football that the overall strength of a team is far harder to stop then just one star player who by themselves isnt enough to turn the tide of a weaker team. A team that can pass and give themselves opportunities all over the field with speed poise and in their quality of direction with the ball is a joy to watch thats football at its best.
In the youth categories the fundamentals gave way to tactical training, we don't see as many young and extremely skilled boys emerging as in the past.
With same, we can go for the Argentina which is also well-balanced and giving his best we need teams like these on all levels and things like these can bring better results instead of going for the star which is never been beneficial like we have only Cristiano Ronaldo which is having nothing to do for his team as there is no strong depth in team, and they are lack of quality which is important while you are going to win big events.
