Agent Federico Pastorello says Arthur Melo is now ready to play for Liverpool.
The on-loan Juventus midfielder has used the international break to pick up his match fitness.
Speaking to Calciomercato.it, Pastorello said: "Arthur played very little last year, then had an operation, planned, in June, thus missing part of the pre-season.
“He wasn't in Allegri's plans, so he didn't train with the rest of the team, so it's normal that arriving at the last day in this condition, from his point of view he needed extra work."
Pastorello added: “Moreover, the difference between England and Italy in this aspect is huge, so there was this need to make up for the physical gap with his teammates."
“Now he has recovered and is at the coach's disposal. I have no doubt that he will do very well in a Liverpool shirt."
