Barca returned to the league's summit at Real Madrid's expense after they blitzed struggling Sporting Gijon 6-1 and Real settled for a 3-3 draw against Las Palmas, but the news was overshadowed by the coach's announcement he would leave at the end of the campaign.
Despite spending eight years with Barca as a player and winning eight out of 10 trophies as first team coach, Luis Enrique divides opinion at the Nou Camp.
His name is often chanted by the vociferous supporters who occupy the Gol Nord end of the stadium. But he has also been subjected to boos and whistles by other fans, who believe he has abandoned the style of play perfected by Pep Guardiola.
A former club of Luis Enrique's, Celta Vigo are fitting opponents for his first game since announcing his plans to end his trophy-laden spell at Barca, although the Galicians have proved difficult opponents for him in recent years.

Real Madrid visit Basque minnows Eibar without Gareth Bale after the Wales international was sent off against Las Palmas, where two late strikes from Cristiano Ronaldo prevented a second defeat for Zinedine Zidane's side in three games.
The French coach admitted something had to change to arrest their recent slide and prevent their bid for a first league title since 2012 derailing. He said:
"We weren't perfect before, but in the last few games we haven't been playing well, but we're going to change that for sure."
