Rayo's defense looks better than Girona's and I think Rayo Vallecano can score a goal today, so I don't rule out a draw in this match. Girona has lost very few matches at home, but so far they have not had matches against strong teams, and besides, Rayo is also playing well away. It is difficult for me to choose a favorite in this match, let my prediction be a draw and Rayo will score a goal.
Basically Girona have been losing on a statistical basis so far this season, playing home and away and also about their head to head results. It is clear that Rayo Vallecano has a better record, so betting on a draw is still a good choice because after all, the factor of Girona playing at home also influences you not to choose Rayo Vallecano.
But if I had to choose and bet on this match then I would still choose Rayo Vallecano, but if we really want to bet in a safe way. So at least, betting on Rayo Vallecano with the option of a double chance and or draw no bet is also a good option.
Anyway, these two teams are not big teams so in terms of quality they are not much different. But if I consider their gains so far this season then I would be able to say Rayo Vallecano is better, and even though in this match Rayo Vallecano will be playing away but it doesn't seem to be a big problem either.
Because after all, of course, they are also used to playing home and away and what's more, at this moment Rayo Vallecano has better home and away results than Girona. Therefore, I'm still pretty sure that Rayo Vallecano has a better chance of getting points in this match.
