Luis Enrique's last season at the Camp Nou.
On 87 points, they are three points behind leaders Real Madrid with just one match to go.
They know they need Los Blancos to slip up and lose in their match at Málaga, something Barça themselves did earlier this season, and if Zinédine Zidane’s side do just that, victory over Eibar would hand the Catalan club the title courtesy of their better head-to-head record.

After having somewhat of a defensive crisis against Las Palmas – the back four there saw Lucas Digne at right-back and Marlon Santos partnering Samuel Umtiti in defence, the situation is slightly better for Enrique.
Aleix Vidal is still a long-term injury absentee, but Sergi Roberto is back from suspension so should play at right-back.
Gerard Piqué has recovered from the virus that kept him out of the game in Gran Canaria, but was unable to train with his team-mates on Thursday, but there’s hope he’ll be ready for Sunday.
Javier Mascherano is also recovering, so one, if not both of them, should be ahead of Santos in the pecking order against Eibar, but Jérémy Mathieu is also injured.
Other than Rafinha, another long-term absentee after knee surgery, Enrique should be able to pick from the rest of his squad, and it would be no surprise to see the front six line up the same way as it did against Las Palmas.
