Genoa coach Gian Piero Gasperini blamed their busy schedule after defeat to Udinese.
Antonio Di Natale and Simone Pepe struck for Udinese inside the final ten minutes to secure the points.
"A good performance, at least up until we went a goal down. We were unable to make the most of our chances and it wasn't easy to play on a Thursday and again on Sunday," said Gasperini.
