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.
I think a well-structured team tactically is much more dangerous than a team with a star who can unbalance the match. Today, tactical obedience and good coaches make much more of a difference on the field.
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.
