I thought everything was over for Villarreal when they got a red card and Athletic Bilbao got ahead later on. However Dani Parejo who is their very experienced player scored the equalizer in the last minutes. I was really surprised to see that. Athletic Bilbao lost points in really comfortable condition and they must have scored their second goal as quick as possible. 
This must be a big relief for Atletico Madrid now as the gap between them is four points now. They can focus on their Dortmund game even more from now on to finish the job. From now on I don't expect Atletico Madrid to lose the fourth position as well. I believe they will make sure of it by beating Athletic Bilbao home in around two weeks.
Atletico Bilbao seems to have to bury their dream of playing in the Champions League next season after the draw from Villareal, currently the chances for Atletico Bilbao to qualify for the Champions League are increasingly difficult because indeed now they have been 4 points adrift of 4th place as the limit of the Champions League zone, like you, I also think if Villareal will lose after their players get a red card, Santi Comesana was sent off by the referee for getting a second yellow card in the first minute of the second half and made Villareal's game start to look a little weak, and even several times the Atletico Bilbao players managed to threaten Villareal's goal, but fortunately Jorgensen was able to perform well to save Villareal's goal from conceding many goals.This must be a big relief for Atletico Madrid now as the gap between them is four points now.

After Villareal's players got red cards, the morale of the Atletico players at that time improved drastically and even they were able to score in the 66th minute to bring the lead to Atletico Bilbao, throughout the second half Bilbao continued to attack and even I think 99% of the victory has been theirs but unfortunately Villareal's penalty goal in the final minute of the game made the score end 1-1, At the same time, and make Atletico Bilbao must be far behind Atletico Madrid at this time with a difference of 4 points.
