The 26-year old has fallen out of favour this season despite impressing when on loan from Grosseto at the end of last term and has revealed he may have to move on for the betterment of his own career.
"I haven't played one minute yet this season," Valeri told Herald Sun's Soccer Confidential.
"We have a new coach (Daniele Arrigoni) who brought in two new midfielders, both play the same position as me and he made it clear that he didn't rate me.
"The weird thing is they bought the rest of my contract and paid a fair bit for it from Grosseto and now I'm not playing.
"If I can't play in Italy after the World Cup then when am I going to play?"
Valeri was in good form for Australia in the recent World Cup and admits he would love to stay in his current surroundings but if things don't improve, may be forced to seek a move with either England or Holland topping his list of potential landing points.
"I'm happy here and my family is settled but if I'm not playing I'll have to leave," he added.
"I wouldn't mind trying something else because I'm not understanding Italian football at the moment.
"I don't want to close any doors. A few people have said I would suit English football but it would be a big lifestyle change - I've been spoilt spending nine years here.
"I've followed Dutch football so maybe there. But first an offers got to be there."
