Barcelona head coach Pep Guardiola says that instinct is more important in his decision-making process than logic or coaching manuals.
The 39-year-old has enjoyed a wealth of success since taking charge at the Camp Nou in the summer of 2008 and has been praised for encouraging an entertaining and attacking style of play.
Guardiola told AS: "I do what I feel. I place more emphasis on instinct rather than logic, for example when making a change of players during a game.
"There are no magic books for coaching. How the team plays, like chess, is the most important thing to being a coach and everything else is secondary.
"Having lost at times I have been more satisfied that when we have won.
"If the team loses, it has been because I have not conveyed my ideas to them correctly."
