I thought the same about the Girona game and Atletico Madrid really finished them off by 3-1.

Actually Girona scored a very early goal to get ahead but this was still not enough to stop Atletico Madrid. Griezmann played a really important role in the win by scoring two goals as well. He is still a very crucial player for this team without doubt.
I don't expect Villarreal to be a huge problem for Athletic Bilbao honestly. Athletic Bilbao already won away by 3-2 before. I expect an even more convincing win this time. The players must be very happy and motivated after winning the Copa del Rey title.

Girona's performance has really declined now so it can be seen that even though they can score first, Atletico Madrid can still control the match and turn things around, Atletico Madrid played much better and they deserved to win this match.
Girona is currently really under pressure after several bad results in their last few matches have reduced their chances of finishing in the top 4.
Villarreal cannot be underestimated, but indeed Bilbao has quite a big motivation to continue to be able to compete to finish in the top 4 and also the condition of the Bilbao team is currently quite good and of course a team that is high in self-confidence has the possibility to win the match This
