Jose Mourinho was booed and whistled by Real Madrid fans last night amid suggestions of dressing-room unrest and a revolt from his Spain players following last week's defeat to Barcelona.

"There is a first time for everything," he said. "It never happened to me at Porto, or at Inter or at Chelsea. It does not bother me. it happened to Zidane, it happened to Cristiano Ronaldo and it happened to the other Ronaldo. If it happened to them then why not to me. They responded with their football and I will keep working hard."

Madrid are five points clear at the top of La Liga after beating Athletic Bilbao 4-1 last night but yesterday morning details of a blazing row between the former Chelsea manager and Sergio Ramos were leaked to Madrid sports paper Marca.
