Betis did not make the best of starts to the season, but the Seville outfit will enter Sunday's clash off the back of a fine run of form. Indeed, the club have won four of their last five matches in all competitions, including a 4-0 success away to Antoniano in the Copa del Rey on Thursday night.
In the league, Rubi's side have picked up 10 points from their last four matches, which is a run of results that has moved them into 12th position in the table.
Betis are nine points clear of the bottom three, while they are actually only five points off the top six, meaning that a win this weekend is likely to see them finish the year in the top half of the division.
The home side ran out 1-0 winners when these two teams last locked horns in February, while Atletico have only actually won two of the last five La Liga meetings, meaning that a victory for Simeone's side on Sunday is far from a forgone conclusion.
Atletico, meanwhile, are currently fifth in the table with 29 points to show from their 17 matches. They are seven points behind the top two - Barcelona and Real Madrid - at this stage but that gap could become bigger should they fail to pick up a positive result against Betis.
The capital giants have only won seven of their 17 league matches this season, which is the joint-lowest number in the top nine. Only Real Madrid (1) have lost fewer matches than Atletico (2) but too many draws mean that the club are not really in the title argument at this stage.
The Red and Whites recorded a 2-0 win over Osasuna last weekend, although that was their first league success since November 10. What's more, they have not been victorious on their travels in Spain's top flight since the end of September, drawing each of their last five.
It is difficult to imagine Atletico catching both Barcelona and Real Madrid at this point; Sevilla in third are just two points away, though, and the capital side will still feel that they are the third best team in the division.
Goals continue to be a problem, though, with just 18 to show from their 17 matches. To put that number into context, only five teams have scored fewer in the entire division.

We say: Real Betis 1-1 Atletico Madrid
Atletico will fancy their chances of picking up all three points in Seville, but it is difficult to back an away victory due to the form that Betis have shown in recent weeks. We fancy a low-scoring draw on Sunday afternoon, which would not be the worst result in the world for either team.
