Juventus coach Max Allegri admits he's unsure if Gonzalo Higuain will stay this summer.
Higuain is being linked with Chelsea for next season.
“I hope Pipita stays, we have to wait for the World Cup," Allegri told Corriere dello Sport.
“I don't know if an offer will come in, then the strength of Juventus is to satisfy those who want to leave.
“I'd want a centre-forward if he does leave, and then [Mario] Mandzukic won't play on the wing next year, he'll return to centre-forward."
On Paulo Dybala, Allegri added: “His future? He's not like Higuain. I spoke to him before he went on holiday and his objective is to have more great seasons with us and then go to a great team to improve.
“If you're playing for Juventus, you have only three chances to improve: Real, Barça or Bayern."
