Mauro Zarate is considering moving on from Fiorentina just months after signing, Italian website Tuttomercatoweb report.
Zarate, 29, left West Ham on a permanent deal in January to sign with the Serie A side, after a mixed spell at Upton Park.
The Argentine played 15 Premier League games in the first half of the season, nine of which were starts, scoring three goals.
His spell at Fiorentina started perfectly, scoring an impressive winner on his debut from the edge of the box, but it has not gone so well for him since, being sent off two games later.
Zarate has started just two Serie A games in total, with six appearances from the bench, scoring twice.
Tuttomercatoweb report he is growing increasingly frustrated with his lack of starts, and wants to hold talks over his future at the end of the season, with it claimed he could push for a move away.
The report cites the Argentine's competitive nature for this, but adds Fiorentina's coach Paulo Sousa is sceptical over his defensive work, and prefers to use him as an impact substitute.
While at West Ham, Zarate had a short loan with QPR after falling out of Sam Allardyce's main plans, and it would not be a surprise to see him look elsewhere if he is not happy.
Zarate may already be regretting leaving West Ham on this basis, throwing away his spot in a promising team too quickly. He made seven more league starts this season for the Hammers than he has done for Fiorentina, and may not find it easy to land a spot at a team competing for a top five place in a big European league if he walks out on the Viola.
