Real Betis 1-2 Barcelona: Raphinha and Lewandowski send Blaugrana eight clear
The Catalans have a big lead ahead of Real Madrid's clash with Valencia
Barcelona sit eight points clear at the top of La Liga after their win at Real Betis on Wednesday.
Raphinha broke the deadlock and Robert Lewandowski extended the lead for the Catalans.
They might have rounded it off with a third when Ansu Fati headed over and instead had to suffer in the final stages, when Jules Kounde chested Sabaly's cross into his own net.
However they held out to take the points and pile pressure on Carlo Ancelotti's champions, who host Valencia on Thursday.
Barcelona took the lead in the second half, shortly after Raphinha had a penalty appeal turned down.
It was the Brazilian who scored, starting in place of the injured Ousmane Dembele.
The superb Alejandro Balde set it up, after a quick early free-kick from Frenkie de Jong.
Pedri was thrice denied by Rui Silva before then as Betis refused to crack.
However after Raphinha scored, Lewandowski netted from close range to ultimately seal the win, despite Kounde's late mistake.
