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.
This will be a difficult match, and Athletico Madrid will not want to lose or draw because they are now in third place in the league standings, and any losses will undoubtedly discourage them from chasing Madrid and Barcelona in league competition. Because Madrid, Barcelona, and Athletico Madrid are chasing the league title, and anyone who loses is a failure because they will no longer be able to get closer to the title. I believe Madrid and Barcelona will not be as strong this weekend as Athletico Madrid, who will face difficult challenges before they can achieve three points, but because they are playing at home, they have a better chance of winning the match. The odds is not really giving good results sometimes, giving Athletico Madrid 2odd and giving Athletic Bilbao 3odd meaning that Athletico Madrid are better then them and playing at home, but probably they can lose the match. But am thinking BTTS can come in the match, because both are doing well and if Athletic Bilbao score definitely Athletico Madrid will score too. And in my opinion the game can be a draw games but Athletico Madrid will have more chance to win the game.
