Atletico Madrid lost the matches against Getafe and Barcelona, two games in which they were in the lead, and have fallen far behind in the race for the top. With almost no chance of winning the championship, Atletico Madrid's motivation is also questionable. They will face Barcelona in the rematch of the Copa del Rey semifinal. So they need to be very careful in this period, otherwise their hopes of finishing the season with a trophy could be completely dashed.
Espanyol are by far the most timid team in La Liga. They don't think about attacking, no matter who the opponent is. However, despite losing away, they have been effective in front of their own fans lately. They don't look as fragile as they did at the beginning of the season. They can score at home, at least against a tired Atletico Madrid, and a mutual score would be a good choice for this match.

Atletico Madrid's inconsistency is always overshadowing them. Their performance have dropped so hard since they get very very strict fixtures, and most probably affect their performance against Espanyol. They're having small odds (1.69), and have big gap compared to the espanyol.
I'm sure many believe they will win the game without getting struggle, but their head to head has told us how they always unable in beating Espanyol. They always getting draw in the last three games in a row. It shows how the result of this match is totally unpredictable.
Yet, i think betting on double chance is a safe bet, but the odds offered by it is pretty small though. Eventhough the risk is high, i still bet on it.
