Barcelona beat a weak team and advanced to the final round, congrats to the Barcelona team. As Osasuna team did not perform well because Barcelona team is one of the richest club and experienced players are in Barcelona club. The chances of scoring goals in this match were more than 3 but only two goals were scored in that match. The Barcelona team had a total of 20 shots aimed at the goal post, but only two were successful and the rest missed.
Osasuna is not a tough team for Barcelona because in many meetings Osasuna can only occasionally win against Barcelona and Barcelona dominates each of their meetings, so it seems like a certainty of victory when Barcelona knows that their opponent in the semifinals will be Osasuna, but facing Real Madrid in the final they will get very strong different resistance, and Real Madrid will have a greater chance of becoming champions than Barca considering both of their performances in Laliga, but this will be a balanced and interesting match and El Classico is always eagerly awaited and even though Real Madrid is the favorite and Barcelona's performance is often inconsistent this season it won't be the guaranteed winner is Real Madrid because Barcelona will probably be very motivated to see their chances of getting the title in other competitions more difficult so will try hard making this their first title of the season.
If Osasuna plays against Barcelona in the semi-final then Barcelona will win the semi-final and qualify for the final. But if there is a match against Girona or Real Madrid in the final, Barcelona can go and play at that time. Girona are considered to be a very strong team this year and the quality of their play looks to be much better than Real Madrid have been in the past. So it will be very difficult for Barcelona to win matches with these two teams
