We knew that Girona would not be able to stay at the top throughout the season, as a result their performance started to decrease and they fell down in the rankings. Barcelona has a big advantage this week, they can win the match tonight and take second place in the rankings. Mallorca is not a strong team, Girona will play against Osasuna and there is a possibility of losing points 
For Girona, winning the ticket Champions League is one of the most important things at the moment, regardless of where they will finish when the season ends. Girona gradual decline in performance made Barcelona lucky, because Xavi had the opportunity to bring his squad to finish in runner-up position. On paper, the Barcelona versus Mallorca match is fairly easy to guess, clearly Barcelona has a much higher chance of securing full points.On the other hand, the Girona versus Osasuna match is also fairly easy to predict, Girona will most likely also be able to secure full points. In the last meeting, Girona managed to beat Osasuna 4-2. Acting as host will help Michel squad start to regain consistency, because in the last five matches Girona has lost a lot of points and was only able to win one match.
This decline in performance should make Michel realize that he as a coach must understand that getting a title is very difficult and prioritize his current position to gain experience in the Champions League even though in the end he will fail in this big competition.
Girona against Osasuna looks like Griona will be the favorite but I am more doubtful for the reason that Osasuna has had a pretty good performance recently so that Osasuna could hold off the attack to share the score and end in a draw.
