The standings of each team in the league should not be used to evaluate how well they have performed this year. If we don't reach midseason, I won't rank a team yet or have high expectations for them to finish the season in such good position. Real Betis position shouldn't be a problem for Barcelona because midseason is when the true competition starts and clubs are always at their best. Barcelona will easily defeat them next weekend since they are ahead of them in the standings and they are no match for Barcelona's expertise as a team.
But, it's not wrong to use this as a statistic for their current match.
Real Betis is one of the clubs that is actually troublesome, in the last match also Barcelona was a little overwhelmed in the semi-final of the Spanish super cup because they had to go to penalties so in this case it is also possible that it will now be difficult for Barcelona.
