Atletico Madrid fans reportedly launched a tirade of racial abuse at Real Madrid's Marcelo after watching their side get demolished 3-0 at Santiago Bernabeu Stadium.
As reported by Sid Lowe of The Guardian, the Los Blancos defender was subject to sickening chants when he joined his teammates on a 20-minute warm-down after the derby mauling:
Real Madrid's Brazilian full-back Marcelo and his young son were subjected to horrific racist abuse by Atletico Madrid supporters after his side's 3-0 Copa del Rey semi-final first leg victory against their city neighbours.
While chants calling Marcelo "a monkey" are despicable enough, Atletico fans who remained in the stadium are also said to have turned their attention toward the left-back's five-year-old son.
Footage of the chants surfaced on Thursday, courtesy of 101greatgoals.com:
Chants changed to "May your father die" when Marcelo received a hug from his child, as noted by Yahoo! Eurosport:
Graham Hunter, Sky Sports pundit and Spanish football expert, believes it is time for the nation to address racist abuse following the latest incident, as reported in Sky Sports' coverage:
They [Atletico Madrid fans] echoed around the empty stadium and I think for all of us who love Spanish football, it's time for us to speak out against this.
Marcelo turned hands on hips, looked up at them, way up at the top of the stands here, shook his head in bewilderment and didn't react.
Spanish football continues to be blighted with incidents of racism.
In November 2013, Real Betis fans were condemned by FIFA president Sepp Blatter for appearing to make racist gestures toward Paulao, their own player, per BBC Sport.
The continued abuse of Samuel Eto'o, who regularly suffered during his tenure with Barcelona, ranks among the most famous racist incidents in recent times. In 2006, the Cameroonian star threatened to leave the pitch after Real Zaragoza fans jeered his every move, as reported by BBC Sport.
Prior to this, UEFA launched an investigation into abuse toward England players during their international friendly fixture with an emerging Spain team, also noted by the same website.
Angel Villa Llona, president of the Spanish Football Association, claimed "there is no racism in Spanish football" during a 2012 interview, reported by Martin Ziegler of The Independent.
Marcelo, who didn't even play during Real's recent win, will certainly vouch against this point.
