Barcelona coach Ernesto Valverde knows they could be crowned champions this week.
"Winning the league is obviously very important," Valverde told reporters at a press conference on Wednesday.
"Ideally we would like to win the league this midweek, but we are playing against a side that are competing for a Europa League place so it will be a difficult match.
"We are still in contention to win three titles, but at the same time we might end up with none.
"Every coach would want to get the league wrapped up as quickly as possible, but we will have to wait and see if we are capable of doing so or not.
"I hope we win it by a comfortable margin like we did last year, but we shall see."
