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.
Atletico Madrid odds @2.04, Bilbao @3.90 and draw @3.40
I think this is a very strange odds and how can bookmakers favor ATM in this match. On the one hand in the last match between these two teams, ATM won by luck and almost ended in a draw. This means I prefer a draw or Bilbao win which I think the odds are more equal to the risk. I believe this match will end with
under 2.5 and a draw has a big chance to happen.
