Barca striker Robert Lewandowski is the runaway top scorer in La Liga with 14 goals, twice as many as anyone else, including two in last weekend’s 4-0 win at Real Madrid.
So should we be surprised by how well boss Hansi Flick has taken to life at the Catalan giants?
“Tactically he has done things very well,” Spanish football expert Guillem Balague told the Euro Leagues podcast.
 “He does owe a bit to Xavi, but that defensive line is the highest in Europe and no other team provokes more offsides.
All that is [down to] Hansi Flick.”
Second-placed Real Madrid and Villarreal, who are third, have seen their games postponed because of devastating flash foods in the Valencia region.
Madrid were meant to be at bottom club Valencia, while Villarreal had a home game with Rayo Vallecano.
Wobbling Atletico Madrid, who have lost three of their last five games in La Liga and the Champions League, host lowly Las Palmas on Sunday at 13:00 GMT.

Antonio Conte’s side are unbeaten in 10 games, winning nine of those, and will be hoping to maintain or extend their four-point lead over Inter Milan on Sunday (11:30 GMT).
“This is what Antonio Conte does in Italy,” said Italian football expert James Horncastle.
“If we go back to matchday one, they lost 3-0 at Hellas Verona.
The transfer window was still open, he hadn’t got some of the players he really wanted, like Scott McTominay – ‘McTomadona’ – and Billy Gilmour.
“Once McTominay integrated he has been very useful playing off Romelu Lukaku, he has the engine to be in a midfield three but also has the energy to break behind Lukaku.
“And they have arguably one of the best dribblers in the world in Khvicha Kvaratskhelia.
I think they will win the league.
Napoli are looking very good.”
But Atalanta, who have Serie A top scorer Mateo Retegui, have only lost once since August and a win would take them to within three points of the leaders.

Sporting will have extra eyes on them when they host Estrela on Friday at 20:15 GMT.
It will be Ruben Amorim’s first game in charge since it was announced he will become Manchester United head coach from 11 November.
It means Amorim will still lead Sporting for their Champions League game against Manchester City on Tuesday, with his final game with the Portuguese club against his old club Braga in the league on 10 November.
