Barcelona sauntered to a 4-1 rout of Granada on Sunday.
Luis Suarez put Barca - without Lionel Messi for this game due to a one-match suspension - in front in the 44th minute with a sublime lobbed finish.
Granada sprung a surprise by levelling five minutes into the second half through Jeremie Boga, before fellow substitute Paco Alcacer restored the visitors' lead in the 64th minute.
The hosts were reduced to 10 men in the 82nd when Uche Agbo was sent off, and a minute later Ivan Rakitic's shot went in off Mathieu Saunier, with Neymar then adding a fourth for Luis Enrique's men in stoppage time, his 100th goal for the club.
"It's the squad that wins you titles," said Luis Enrique to reporters. "It's up to us to balance the injuries and suspensions against our fringe players.
"I'm very proud of Alcacer, I've been praising his attitude all season because he's always there for the team.
"He's been superb, he's been involved in two goals tonight - scoring one - and he's been a constant threat."
