It turned out to be an unforgettable first 'Clasico' match for Jude Bellingham who scored two goals including a stoppage-time winner to lead Real Madrid to a 2-1 comeback victory at Barcelona in the Spanish league.
They were Bellingham's 12th and 13th goals in 13 games in all competitions since he joined Madrid this summer, including a Spanish league-leading 10 goals in 11 rounds.
Barcelona went ahead in the sixth minute through former Manchester City midfielder Ilkay Gundogan's first goal for his new club. The hosts also hit the woodwork twice before Bellingham equalized.
Bellingham was kept in check by Barcelona's Gavi Paéz until he found space well outside the box to unleash a strike in the 68th that swerved past Marc-Andre ter Stegen and hit the corner of the net.
Bellingham then tapped in the stoppage-time winner when a deflected ball fell to him in front of the net.
Madrid remained top, level on points with second-place Girona. Barcelona is in third place at four points back.
