Napoli president Aurelio de Laurentiis is unsure about signing Barcelona winger Gerard Deulofeu.

But he is prepared to sign the Spain international if his coach requests it.

"(Maurizio) Sarri will have the last word in this type of acquisition," De Laurentiis said on Italian radio.

"He alone knows the time the player will need to perform on the field, and the coach must ensure that it will not take six months for that to happen.

"(Simone) Verdi would be suitable because he has already been trained by Sarri, whereas Deulofeu would be a leap into the unknown."
