Bilbao has a good record in the previous meeting, so it will be more motivation for them to win this match. If they win, then they will narrow the points gap with Atletico Madrid, it is a good opportunity for them. It is quite interesting when looking at the records in the last 5 matches of both clubs, because they both have 3 draws and 2 wins, that is the same record. So I agree that this will be a tight match, and if a draw occurs, then it is something natural and not surprising at all.
Athletic Club is in a very good situation now. We have not seen Athletic Bilbao lose a match for a long time. And Athletic Bilbao's defense is quite strong. However, Atletico Madrid is not a weak team either. They are fighting for the title this season.

Atletico Madrid vs Bilbao matches are always very competitive. I checked the statistics of the last 5 matches between them. We have seen Atletico Madrid win the last two matches. And Athletic Bilbao won the previous three matches. But every match was very competitive.
There will be a team among the top 3 teams that will drop a point this weekend, the reason why I said that is because Atletico Madrid is playing against Atletico Bilbao, Real Madrid is playing against Real Betis and Barcelona is playing against Real Sociedad, this show that Real Madrid, Barcelona and Atletico Madrid are going to face some tough teams in La Liga and if they did not take care they might end up draw or lose the game, the top teams can also win their games because they are in good shape.
Atletico Madrid is playing against Atletico Bilbao and both teams know how to play against each other, if we check both team's matches against each other they find it difficult to defeat each other but with the performance of Atletico Madrid this season I am still thinking that Atletico Madrid can win the match and if they can not win the match they can only draw because Atletico Bilbao can't defeat Atletico Madrid with their current performance.
