I deal with football from a realistic, logical point of view.
A good thing for footballers is not to think too much, especially when you've got to move to a big team like Liverpool, because that's when you start to confuse your mind.
Football linemen are motivated by a more complicated, self-determining series of factors than the simple fear of humiliation in the public gaze, which is the emotion that galvanizes the backs and receivers.
I don't think Wayne Rooney would be affected if you booed him, that's just how he is, but others go under. They really suffer with it. I think I'm somewhere in the middle... now. I've become tougher as I've got older.
In England, I always liked the way Terry Venables worked.
Although he may not be human, it’s good that Messi still thinks he is.
In football, 80% of the game is played in your head; the other 20% is physical and tactical.
I think in football, most of it is just mental.
In my own opinion, psychology in football is far more important than anyone believes, including the coaches.
It's always like that: strikers have to score to be confident.
But concepts around how a team functions, the importance of the relationship between football and the person, how you develop both, are always valid.
It's quite possible that Beckham suffers from a mental block at big tournaments
