Osasuna are shown as the favourite side in the game against Sevilla. If it was in Sevilla's home then maybe things would have been the other way around. Anyway honestly I don't see any problem with this situation now. Because Sevilla are one of the most unreliable teams in the La Liga currently.
I know they won against Las Palmas home to finish their losing streak. However right after that they couldn't beat Lens home in the Champions League. They got a draw there. There are still serious problems and Osasuna are one of the teams that can take advantage of this. I don't expect them to lose to Sevilla.
At the moment, everything looks exactly like this, which I agree with the bookmakers, although Osasusa’s advantage is not at all large and this is understandable. I also thought that Sevilla should have beaten Lens, because Lens started this season even worse, but in the end it all ended in a draw. Osasuna and Sevilla are home teams, especially Seville, and it was in the home match that they managed to beat Las Palmas, but in the away match with Osasuna it will be difficult for them, I doubt that they will be able to win.
It is not possible to speculate about Sevilla's performance. They lost their first three La Liga matches, with a narrow 1–0 win in the fourth. They could not win against Lens in the Champions League match. Overall the performance of this team is still quite weak and erratic. But the fact is that the Osasuna team is not in a good position either. Their achievement is only 6 points in 5 matches. However, considering the performance of the match between these two teams, Osasuna must be ahead. Osasuna have won their last three matches against Sevilla. But I think today's match is most likely to be a draw. Maybe the match will be ended in a 1-1 draw.
