Milan try to keep title push afloat in Rome as Inter host Genoa

Napoli and coach Gennaro Gattuso are under increasing pressure with three defeats in their last five league games, and elimination from the Europa League.
"The criticisms are deserved, things are not going well. The main one responsible is me," insisted Gattuso.
"It's understandable that I'm massacred, but leave my players alone.
"We need actions, not words, but we mustn't get depressed. We must look forward."
