The conference league is the only hope for villareal and bilbao to play in european competition, but I think in this case villarreal have a better chance in my opinion to play in the conferencee league next season, facing barcelona which is no longer concerned with points of course villareal maybe can get a win in this match, while bilbao who face sevilla will of course get stronger pressure in the match, sevilla indeed have now secured a top 4 position but I think they will aim for the three points against bilbao later because they want to ensure a place to be in over atletico.
Villareal will not easily beat Barcelona even though they are no longer concerned with points to qualify for the Champions League next season. Barcelona are already safe to qualify for the Champions League, but they also don't want to end the season with a loss to Villareal.
Barcelona vs Villareal and Sevilla vs Bilbao matches in my opinion will be very interesting because one of the away teams will ensure themselves to qualify for the European Conference League next season. Sevilla shouldn't be losing at home, and neither should Barcelona.
I don't know if Barcelona is going to play a very sweaty game against Villarreal because they have already secured their position in the league. so I don't think this match will have any importance to Barcelona.
Sevilla should play better in home conditions. They have the match against Athletic Bilbao and I believe Sevilla should be the winners because they will certainly get some advantage in home conditions.
