Also that specifically: There is such thing as trying too hard. You must have heard of that phrase. It's not about working the hardest way, it's about working the smartest way and when you are working too hard, when you want too much, your focus gets blurred so does the level of your decision making drops. You get in the state in which you play worse than you did before. A leader is supposed to make everyone around him focused, not invested so much into the game that they make ridiculous decisions. Have you ever seen players like Busquets, Kroos, Pirlo, Xabi Alonso, getting hyped up and energetic on the pitch? No, ask yourself why? Football is about making a good gameplan and despite the possibility that things might get out of hand, leaders job is to assure everyone that gameplan is the right one to play, and that way bring back their belief into it, and tell them to stay focused and do the job they are supposed to do in the gameplan. It's the quality of perfectly executed gameplan that will determine the outcome of the match, not how hard players are running on the pitch. What a good leader basically does is he reassures teammates that this gameplan is the best way to win and reminds them to be focused and stick to their assigned roles. That's aaaaall. No big deal.
