European football's governing body Uefa has launched a disciplinary case against Barcelona's Sergio Busquets over alleged racism in the Champions League semi-final with Real Madrid.
Real posted a video on their website before the second leg showing Busquets allegedly calling full-back Marcelo "mono" (monkey) in the first leg.
The case will be heard this weekend.
The incident was one of several in a heated tie between the Spanish rivals, which Barca won 3-1 on aggregate.
