Genoa coach Gian Piero Gasperini is demanding more from his players after their 2-0 win over Europa League opponents Slavia Prague.
"We have vast margin for improvement," insisted Gasperini. "We can do even better and must work hard to improve."
"I have a very good squad at my disposal and everyone will find their own space between the Serie A and continental games.
"All they have to do is keep working hard and improving all the time."
