Giuseppe Rossi and Mario Gomez both struck twice in the rout.
“I am not surprised by Rossi’s form, as he is someone who has always been able to find the net. We know he can improve further and with Gomez they make the perfect couple,” Montella told Sky Sport Italia.
“I was really impressed by the final 20 minutes for Gomez, as he fought hard in every position to defend the result.
“We played a perfect opening 20 minutes and thought we had finished off the game, but we slowed the tempo in the second half and allowed Genoa back into it.
“We need to grow, as again we conceded two goals tonight. We ought to be more solid in defence.”
