Real Madrid goals can reach 3-4 goals against Betis. Real Betis is not even up to Real Madrid standards to start with this season, they're completely below elite clubs this season and that simply means they don't pull any significant threats against elite clubs. Carlo Ancelotti have worked out his plans and he's just aiming for the possible best results in matches to be played by the club he has worked so hard to manage. This is supposed to be a game we shouldn't be talking about because I'm pretty sure of Real Madrid will record massive winnings and three points is fully secured.
This match is an opportunity for Real Madrid to distance themselves from Girona's shadow, because Betis is not a tough opponent for Real Madrid. In fact, this will benefit Real Madrid. If they win this match, it will be very different from Girona hosting Barcelona, which is a strong team and not it is impossible for Barcelona to suffer defeat at home, of course Barcelona will provide resistance to its competitors and reduce the points in the current standings, even though Real Madrid is predicted to have 3-4 goals, but in my opinion it is too big to predict at this time because Betis is considered a good club. quite well from their last five matches, because that could be a benchmark that Betis could be a threat to Real Madrid tonight.
It would also allow Barcelona to get very close as well, Girona would stay at 38, Real would be 41, and Barcelona would get to 37 as well, quite close to each other. One more game and Barcelona would be right on the tails of Real Madrid as well, and that's a good thing for them, Real will eventually lose points somewhere, they can't just have full winning streak until the end of the season, they will lose points eventually and Barcelona will lose points too, so they will hope that they lose a lot less points than Real does, and win their game against Real and get ahead of them.
So, Barcelona has to care about this game a lot, otherwise they are going to have way too many points difference and I do not think that they will be able to recover that.
