Real are wary of the individual quality at Bayern.
"There are many elements to take into consideration," said Butragueno.
"Firstly there is history. Bayern are a team with great pride, who have top quality players such as [Arjen] Robben, [Franck] Ribery, [Thomas] Muller.
"Secondly, we have to play our best game and not make mistake. Hopefully it will inspire us to the final."
