Madrid are top of the Spanish league by one point from Barcelona, but Zidane's side have two games in hand. Barca play at home to fourth-from-bottom Leganes later on Saturday. "Bale is a very important player for us. We know the quality and speed that he has, and the damage he can cause the opposition," Frenchman Zidane added. "He's very happy to return to the team, to be with us, and be able to play again." Espanyol, managed by former Watford boss Quique Sanchez Flores, are ninth in La Liga, 17 points behind Madrid.
