Honestly I still doubt whether Barcelona can win this match or not. Based on individual and team quality of course Barcelona is better than Real Betis and the odds also favor Barcelona to win the match. But we see Barcelona has suffered 3 defeats and that was from unpredictable teams like La Palmas, Sociedad and Osasuna. On the other hand Real Madrid only suffered 1 defeat and that was against Barcelona. So I think Barcelona is still inconsistent with their performance this season.
Inconsistent? Then if they are inconsistent unlike Madrid, why are they leading the standings even if we assume that Real would win their extra matches left? Also, Real has suffered two defeats not one, just the other day it was beaten by Athletic, they have the same number of losses as Braca in the last 5 games, at least check the data before you make assumtions like these ones.
Either way, penalty kick, 1-1, penalty, and Flick gets himself a red card and leaves the stadium it seems.
