why sergio presses

Guardiola said: "From the beginning we spoke with Sergio. He had to know we are here to help him in the way we play, to create as much chances as possible and to have more chances to score goals.
"But he has to help us. It is not enough to receive the ball from his team-mates. He has to help us in the first pressure, running a lot, in the build-up movements.
"When that happens, and you are involved in both the defensive tasks and the offensive, you are more brilliant. You cannot be brilliant with the ball if you disappear when you don't have the ball. It is impossible.
"Football is a connection between what you have with the ball and without the ball and now Sergio, in the last two games, did it."
