The hosts, though, have won five of their last seven home games and will provide a stern challenge for the Blaugrana.
Eibar have lost all seven matches they have played against Barcelona in La Liga and dabblebet offer them at 6/1 (7.00) to claim a first ever win.

Having seen his team's lead cut to seven points at the top of the table, Valverde is likely to field a strong team despite the return of the Champions League.
Eibar could welcome back influential midfielder Pedro Leon after eight months out, while striker Sergi Enrich remains unavailable with a knee injury.
Barca effective on the road
The Catalans have won nine and drawn three of their 12 away games this term and Barca under Valverde have found ways to win tough games.
However, the only real thrashing they have handed out on the road was 5-0 win at Real Betis and the Blaugrana should expect another challenging - but winnable - encounter when they face Eibar.
Tips and predictions
Barca to win and under 3.5 goals is a solid pick at 13/10 (2.30), and has paid out in seven of their nine away wins this term.
