Kylian Mbappe put Madrid ahead but a dominant Barcelona hit five in response before their goalkeeper Wojciech Szczesny was sent off in the second half.

LaLiga leaders Real recovered from that setback and are on a five-match winning streak ahead of defending the Super Cup in Jeddah, Saudi Arabia, but coach Carlo Ancelotti is cautious.

The Catalans beat Real Madrid in last year's final and will face their bitter rivals again Sunday after Los Blancos beat Atletico Madrid in an eight-goal thriller in the first semi-final in Saudi Arabia.

"These moments can only be experienced here. All of us who played gave our all," said Brahim Diaz.

The two sides met later twice in cup finals during the 2009 Super Cup and 2011 Super Cup, with the Black and Whites winning the former and the Sky Blues having the last laugh two years later.

The May 30 final will be the first cup final between the country’s two most popular football clubs in 12 years. The last time these two teams met in a final was in the 2011 Super Cup, where Abahani came out victorious.

Real Madrid president Florentino Perez again insisted on the idea of a European Super League when speaking at a club members assembly on Sunday.
