Valencia midfielder Dani Parejo was abused by Real Madrid fans as he made his way in to the Bernabéu to watch the Champions League semi-final against Atlético.
Parejo scored against Madrid on Saturday
Parejo, who came through the ranks at Real Madrid, scored a superb free-kick at the Bernabéu on Saturday, to momentarily draw Valencia level, before Marcelo restored Los Blancos' lead.
Nonetheless, his strike had Zidane's side anxious for a short while. Madrid have little margin for error in the La Liga title race, with Barcelona looking to take advantage of any slip-ups.
Madridistas: 'You nearly lost us the league!'
The one-time Queens Park Rangers midfielder was greeted by shouts of 'you nearly lost us the league', as he entered the Bernabéu.
Although he emerged through the Real Madrid C and Real Madrid Castilla route, Parejo has previously confessed his fondness for Atlético. As a result, his presence at the Champions League semi-final did not go down well.
