If you do not believe you can do it then you have no chance at all.
Football is an art, like dancing is an art - but only when it's well done does it become an art.
I believe in work, in connections between the players, I think what makes football great is that it is a team sport. You can win in different ways, by being more of a team, or by having better individual players. It is the team ethic that interests me, always.
Maintain that motivation to go from A to B and to keep your focus on that target without any weakening. That is called tenacity; stamina in your motivation.
It's silly to work hard the whole week and then spoil it by not preparing properly before the game.
At a young age winning is not the most important thing... the important thing is to develop creative and skilled players with good confidence.
