Bilbao is a city that has always been known for its rich history and culture, but it's also home to some of the best football teams in Spain. One such team is Athletic Bilbao, who have had an incredible season so far in La Liga.

One of the key aspects of Athletic Bilbao's success this season has been their exceptional defending. The team has conceded just seven goals in 15 games, which is an impressive record for any team in La Liga. This is largely due to the work of their defense, which has been solid throughout the season.

One player who has stood out in terms of his defensive contributions is Ruben Dias. The Brazilian center-back has been instrumental in helping Athletic Bilbao keep clean sheets, and he has been praised by many for his excellent positioning and tackling ability.

Another standout defender for Athletic Bilbao this season has been Marko Grujic. The Serbian midfielder has been a regular starter in the backline, and he has shown great versatility both defensively and offensively. His crossing ability and passing range have helped create scoring opportunities for his teammates.

Overall, Athletic Bilbao's high-quality performance in La Liga can be attributed to their strong defense. With players like Ruben Dias and Marko Grujic leading the way, they have made it difficult for opponents to break down their defenses. As the season continues, it will be interesting to see how Athletic Bilbao performs and if they can maintain their current level of excellence.
