Raphinha scored twice as Barcelona overcame a two-goal deficit to secure a crucial 4-3 home victory against rivals Real Madrid in a pulsating Clasico on Sunday, edging them closer to the LaLiga title.

The victory extends Barcelona's lead at the top of the standings to seven points over second-place Real Madrid with three matches remaining. One more victory will clinch a 28th Spanish league title for the Catalans.

Barça earned a fourth consecutive victory over Madrid in all competitions this season, and their second in less than a month, in a chaotic match in which both sides showed their usual defensive weaknesses.

Barça seemed a much stronger and well organised team overall, dominating possession and creating several chances that were denied by an inspired keeper Thibaut Courtois, who prevented Real's loss from being by a larger margin.

Hansi Flick's side can secure the LaLiga title as early as Wednesday, should Real Madrid fail to win at Mallorca. However, regardless of Madrd's result, a Barcelona victory in their city derby against Espanyol on Thursday would guarantee the championship for the Catalans.

Real Madrid made a blistering start at the Montjuic Olympic Stadium, with a brace from Kylian Mbappé giving them a two-goal advantage.

However, Barcelona responded swiftly with Eric García, Lamine Yamal and Raphinha all finding the net within 15 minutes to overturn the deficit.

Madrid thought they had earned a second penalty in the 43rd minute but it was overturned due to an offside in the build-up and, one minute later, a costly error by captain Lucas Vázquez gifted Raphinha the goal that extended Barça's lead.

Barcelona came back strongly in the second half and had several chances denied by a string of stunning saves by Courtois.

They were shocked, however, when Mbappé reduced the deficit in the 70th minute after a quick counter-attack by Vinícius, who ran up the right and put it on a plate for the France forward to complete his hat trick.

Yet last year's champions could not recover, leaving them on the brink of a season without silverware.
