The 'no to racism' banner was shown before Real Madrid's Champions League tie with Benfica
Real Madrid have launched an investigation after a supporter allegedly performed a Nazi salute before the club's Champions League win against Benfica on Wednesday.
Prior to the kick-off at the Bernabeu, a fan appeared to make the fascist gesture as the television cameras panned around the 83,000-seater stadium.
The fan was identified by security staff moments later and ejected from the ground.
Real beat Portuguese side Benfica 2-1 in the second leg of their knockout round play-off tie to progress 3-1 on aggregate to the last 16 of the Champions League.
