"It's about trying to be superior to a rival and dominate in the game, which is having more chances than your opponent and they have fewer than you," Valverde said in a conference with the Basque Football Federation and the Basque Committee of Coaches.
"There are times when you have possession and not chances and without chances, you don't have that dominance, but to have chances, you have to have the ball.
"I like being the master of the ball because you take it off your opponent. The question than is if you're deep or not with that ball.
"Each person has to see how they feel at ease to be able to get their message across."
"Ultimately, possession is a way to win a game.
"It's a bit magnified by the media, but it's nothing more than criteria.
"If you want to be aggressive with the ball, you also have to be aggressive without it.
"In my case, it's about wanting to take the initiative of the game and that happens because the opponent don't want to play."
