Ancelotti compared the performance to hearing a cat drown, which rankled sensitivities in Russia to the point where some questioned how Blues owner Roman Abramovich could tolerate such an insult. But Zhirkov said he had no problem with book.
"I laughed," he said. "How else should I react?"
"Ancelotti was lucky," quipped the one-time Russia midfielder. "He didn't hear me sing!
