As we can see Girona took advantage of the momentum well. So Girona steps in La Liga are very well calculated. They know that no club can interfere in Real Madrid and Barcelona eternal rivalry in La Liga so what Girona can do is take advantage of the situation. Girona could lose to both clubs but the probability with the other club is actually higher. So this gives Girona a breath of fresh air sacrificing matches against Barcelona and Madrid but on the other hand they are fighting for big opportunities with the remaining clubs. For me, Girona strategy has been quite effective so far, with the result of 13 matches and one loss being a big achievement.
Your point is very valid and I think it's exactly the strategy Girona has been using since this season because, on a second taught, if they win every other team and loose to only either of Barcelona or Real Madrid, they will still continually climb and maintain the top position on the table,
The only time it could really cost them may be toward the end of the season if they point happens to be all they will need to rank up the table. At that point they will need to win but then I just hope their consistency is enough to keep them going and if the only challenge they have happens to be just this two teams then they don't have much issues because the challenge will have Little effect on them and in worse case they will qualify for champions league buy they can be sure to finish top four
If Girona can win all the other clubs and lose to Barca and Real Madrid, I think that they will have no challenge of winning the league this season and I love this their strategy, only if they can make it work out by making sure that they win all those other matches. The reason why I said this is because I still believe that along the line Barca and Real Madrid will still loose some matches.
I don't think that it will be easy for Girona not to loose any match except that of Barca and Real Madrid because there will be some unforeseen challenges that is bound to happen in front, for example the players might have injury which will affect their performance. I think that the league is open to any the top three clubs to win. From next year, we can tell if Girona will continue with their match consistency
