Barcelona:
Ernesto Valverde's men drew against Valencia last weekend, meaning they sit four points ahead of the second-placed team.
Lionel Messi should return to the starting XI after being rested for the Copa del Rey win against Real Murcia on Wednesday.
Gerard Pique was suspended for the game at the Mestalla, but is also in line to return for this match.
Celta Vigo:
The visitors can take confidence from the fact that they have beaten Barcelona at home in each of the last two seasons.
Their away record, however, is not as easy on the eye. They lost 5-0 at the Nou Camp last season and 6-1 the campaign before.
Bar a calf injury to centre-half Sergi Gomez, they have a fully fit squad to choose from.
