Higuain can become an extra-terrestrial - Sarri

Maurizio Sarri says Gonzalo Higuain can "become an extra-terrestrial" after watching the in-form striker fire Napoli to the summit of the Serie A standings on Monday.

Higuain struck twice as the Partenopei defeated 10-man Inter 2-1 in a dramatic encounter at the San Paolo to displace Roberto Mancini's men at the top of the table.

Sarri was full of praise for the Argentina international, who now has 12 goals from his 14 Serie A outings so far this season, but argued that the former Real Madrid striker can still improve.

"It depends on him," the Napoli boss told Sky Sport Italia. "If Higuain makes another step forward psychologically, then he can become an extra-terrestrial.

"He needs to be even more determined because he can become even better."
