The agent of Giuseppe Rossi says with Villarreal the young Italian can match Primera Liga stars Lionel Messi and Sergio Aguero.
Federico Pastorello told Radio Calciomercato.com : "He's getting better after his injury and is on the road to recovery.
"He's in the middle of his recovery and we hope he's back before Christmas.
"Villarreal want him back so he can maintain his good progress and not lose ground on two rivals for the top scorer's award, Messi (Barcelona) and Aguero (Atletico Madrid)."
