Cinny, you're right, Deportivo weren't the best in that game, but I personally think you could put it as much down to a good performance by Zaragoza as to poor play by Deportivo. If we're going to look at poor recent performances, then you could just as easily look at Atletico in their 1-3 defeat at home to Betis in their last-but-one home game.
Snowman, think you're being pretty harsh on Zaragoza, especially on the basis of just one game. They had an off day in front of goal, and although you're right that the goal was down to an error by the Depor keeper, they created plenty of chances, something they've been doing all season. They've scored 34 goals in 18 games at home, and they've only failed to score in 1 home game. Their front 2, Milito and Oliveira, have got 29 goals between them (only Real Madrid, Atletico Madrid, Sevilla and Mallorca have strike partnerships with more goals than them).
Despite that, I still can't convince myself to back Zaragoza at that price
