Wolfsburg sporting director Klaus Allofs considers Cristiano Ronaldo a more selfish player than Lionel Messi, but acknowledged his mentality benefits Real Madrid.
Ronaldo and Messi have split the Ballon d'Or for the past eight years, with the Argentine star winning five to the Madrid talisman's three.
Allofs says Ronaldo plays a more individual role compared to Messi, but his record in front of goal proves it works out well for Zinedine Zidane's side.
"I was asked the other day on German television about Messi and Cristiano. They are two incredible players," he told AS.
"In these cases, you have to see which players they have around them. With Messi, for instance, he has Luis Suarez.
"Ronaldo plays more for himself, but his magnificent statistics help the team get a result. That's why he scores so many."
"In the Bernabeu many things can happen. Things will happen that we cannot yet imagine, incorrect refereeing decisions, for example," he said.
"This is not certain, but it can happen and we must be prepared."
