Real Madrid captain Sergio Ramos understands the whistles directed at Cristiano Ronaldo, but believes fans should be more thoughtful.
Ronaldo was jeered before he struck a hat-trick to inspire Madrid to a 4-2 extra-time win over Bayern Munich to send them into the Champions League semi-finals.

Ramos said the demands of Madrid fans meant he could see why Ronaldo was jeered by supporters in the quarter-final second leg.
"I understand the public and Cris," he said.
