After a few days of relative calm, Ronald Koeman returns to the scene and has addressed the press before this Sunday’s match against Valencia at the Camp Nou (9pm, Movistar LaLiga). The coach is still a week away from three games in which the little credit he has left at the helm of the Barça bench will be played. “We have to improve on things that we have lacked in recent games. Especially in defense. We play at home and we want to win,” Koeman said strongly in the first response.
