What managers say
Eusebio Sacristan: "Both sides were evenly matched from start to finish, so I consider this an excellent three points. We played a good game. We kept a lot of possession in good areas, forced attacks and kept our defensive shape. Malaga put everything into this game, which makes the points even more valuable." [via Football Espana]
Luis Enrique: "It was a very complete performance [against Las Palmas] and wonderful from a defensive perspective. It's a match that strengthens all of us and we're coming on very well. All the players are important to the team. Everyone wants to play more, but what matters is the good of both the team and club." [via Football Espana]
