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.
