The only way Osasuna can challenge Barcelona in the match and end it draw is if they play well, I don’t see Osasuna winning the match, some Barcelona players will not play the game and even if they do they will not play well because they will be very tired, player like Raphina and Araujo will not be playing the match and even if they do they will not play well because they will not have enough time to rest as they are playing the both players are playing their last international match tomorrow morning and the match against Osasuna is on Thursday.
Osasuna is one of the teams that has defeated Barcelona this season and Barcelona will not let that happen again, Barcelona can not play well if Raphina and Lamin Yamal do not play well, and without Raphina their best player they can not defeat Osasuna easily, it depends on how Osasuna play well in the match because sometimes the small team can not hold the pressure of the big team.
The only thing Osasuna can count on in this match is their defense, that they will be able to hold out for 90 minutes without conceding a goal. But I doubt it very much, Barcelona's attack is very strong and I think that Osasuna has no chance even for a draw in this match. I don't know how Osasuna managed to beat them in the first match, it was only the beginning of the season, now Barcelona has definitely become a different team. The odds 1.3 for Barcelona to win, I thought, would be less.
I don't think Osasuna have players that will make this game difficult for Barcelona to win, and if you look at their defensive in their last game, you will agree with me that Barcelona will secure victory from this game. I know Barcelona coach don't like to use their talented players to play small team some time which I know the coach will not try such thing, because he have to use this game to encourage their fans that they are still standing well to lift the trophy.
You will not regret for your prediction once you predict for the favour of Barcelona to win, because we have seen some excellent performance Barcelona players has display to beat Real Madrid and other strong teams this season.
