To be honest, I think the number of hearts is a good indication of how effective your team tactics have been. Admin has always said that success is not all about team tactics and I think he means that individual brilliance also comes into it. You can see this with direct play and/ or defensive tactics where you team might get outplayed but your striker scores the winner from your only shot of the game or sometimes you spot and exploit a weakness in an opponents team e.g a particular flank or float crosses. Howver, in my opinion the only way to control a game is through team tactics, if you are not the strongest team, there are things you can do that will you a chance but you will need luck to be successful.
