Barcelona will still be able to win at home when hosting Osasuna even without two mainstay players like Raphinha and Araujo. Because Osasuna is not a dangerous team in La Liga this season and when they are guests at the home of other teams Osasuna also does not have more ability so the possibility of Barcelona winning is very large even though I did not make a prediction with more goals against Osasuna. Because Barcelona only needs to win by any number of goals as long as Barcelona can secure full points even if only by one or two goals.
Yes, that's true, but in the first match Osasuna somehow managed to score 4 goals against Barcelona and beat them, although in fact this is a rarity, Osasuna often scores few goals, but they took points in matches with Real, Real Sociedad and Athletic Bilbao, so this team knows how to play with strong teams. I also expect Barcelona to be able to beat Osasuna, especially at home, but this may not be an easy victory, Osasuna has many draws, they know how to defend.
Barcelona needs to try their best in order for them to win Osasuna, otherwise, they'll have to fight till the end of the season on pressure to make sure Madrid does not take over them. I feel this is the best opportunity for Barcelona to widen the point gap, because we don't know the unforeseen challenges that might come up in future before the end of the season. It's an important match for Barcelona.
