Ronaldo stepped in after the over-enthusiastic fan vaulted the barriers and rushed towards the team bus as it prepared to leave for Valdebebas.

Burly security men quickly tackled the intruder and looked set to drag him away.

But the Portuguese captain looked sympathetic and walked over to talk to the fan, telling the heavies to stand down.

Zinedine Zidane's side will equal Madrid’s longest unbeaten run in all competitions if they avoid defeat at home to Dortmund.

Zizou’s impact on a squad seemingly going nowhere under Rafa Benitez just 12 months ago is astonishing.

And now he has them on the brink of equalling Real’s 34-match unbeaten record, set under Dutchman Leo Beenhakker in the 1988-89 season.

Madrid haven't lost since April in competitive competition and have already qualified for the knockout stage of the Champions League, as they look to defend their title.

But they must beat Dortmund tonight to top Group F after high-scoring draws against Legia and the German's in their first meeting.
