Betis - Barcelona is such an interesting match that both of them can be the winner at the end of it. Because Betis are also one of the teams that are having an incredible season. This is their biggest success in the La Liga for so many years. And they still have a chance for even joining the Champions League. They mustn't turn this opportunity down that easy. As Atletico Madrid also have a very difficult match against Real Madrid, I think Betis have a big opportunity to catch up with them maybe. I'm just thinking of betting on both teams to score and enjoy the match. 
Real Betis have a good chance to close the gap with Atletico Madrid by winning this match. However, their recent performance is very bad. They have not won in the last 3 matches. Now it will be more difficult for them to win against a strong team like Barcelona. Barcelona, on the other hand, will definitely want to secure second place in the points table. And they will play with the goal of winning all the upcoming matches. Since Real Betis is not in good form, I think Barcelona is the favorite in this match.This season we have seen Barcelona lose to even the weakest teams. So if Real Betis plays well, they have a chance to win. And you say that, Real Betis have a chance to score 12 points in the next 3 matches, if they can play well. However, Real Betis are in such a weak form now that it is difficult for them to win against Valencia and Granada. However, the players will be confident if they can win against Barcelona. This will increase the chances of winning the upcoming matches.
