Athletic Bilbao is clearly favorite here.

Athletic is in great form, playing great football and solving the problem they had in the last years: lack of goal and danger upfront. William’s brothers are performing very well, while others are also contributing scoring goals.

At home they are a very strong team (5 victories, one draw and two defeats; just 4 goals conceded) because they play there with a lot of pace, intensity and it’s very difficult for rivals to stop them, because Athletic attacks from everywhere: wings, set pieces, counters, fast football…

They are now 7th on the table but I believe they have a clear target of achieving european positions, Conference League (6th) at least, because the squad has quality and ambition for that.

On the other hand, Osasuna is performing well too, but is an irregular team. They are in a quiet 9th position, so don't have pressure for points. Playing away they decrease their level a lot, scoring just 5 goals in 8 games, and winning just 2: Celta and Almeria, both relegation teams.

The main reason to bet against them is their last game against Real Sociedad: lost 2:0 and were totally outplayed. And Real Sociedad is a very similar team to Athletic in the style (high pressure, intensity…), tactics and quality.

Key CB Unai Garcia is out, and will be replaced by Aridane who is in terrible form, without too much activity because always when he plays, makes huge mistakes due to lack of confidence/form.

Last season both teams were on similar level as they are now, and Athletic won both games: 2:0 at home and 1:3 away, outplayed Osasuna twice.

毕尔巴鄂竞技显然是最受欢迎的球队。

竞技状态很好，踢得很好，解决了他们过去几年的问题:缺乏进球和前面的危险。威廉的兄弟们表现得非常好，而其他人也为进球做出了贡献。

在主场他们是一支非常强大的球队(5胜1平2负;只丢了4球)，因为他们在那里踢得很快，强度很大，对手很难阻止他们，因为竞技的进攻来自各个方面:边路、定位球、反击、快速足球……

他们现在排在积分榜的第7位，但我相信他们有一个明确的目标，至少在欧洲联赛中排名第6，因为他们的阵容有实力，也有雄心。

另一方面，奥萨苏纳表现也很好，但这是一支不正常的球队。他们安静地排在第9位，所以没有积分压力。在客场比赛中，他们的水平下降了很多，在8场比赛中只进了5球，只赢了2球:塞尔塔和阿尔梅里亚，都是降级球队。

赌他们输的主要原因是他们上一场对阵皇家社会的比赛:2:0输了，完全被击败了。皇家社会在风格(高压力，强度……)，战术和质量上都非常相似。

关键后腰乌奈·加西亚缺阵，他将被状态糟糕的阿里达内取代，他没有太多的活动，因为当他上场时，总是因为缺乏信心/状态而犯巨大的错误。

上赛季这两支球队的水平和现在差不多，竞技队赢了两场比赛:主场2:0，客场1:3，两次击败奥萨苏纳。
