Having as an example the top100 from asso imo is totally wrong as most of them are there because of their trick skills.Always teams with mutant or very well trained players were a step forward to the normal teams.
Those player are doing all the "hard work".
Off course you can influence the game,as most of times when you or your opponent make a substitution,a goal will be scored in the same minute,but this is just because you trigger an action,not because you necessarily done a good move(that's why I'm 100% with Khris in what he is saying)
