Martinez Quarta is considered one of the best defenders in Argentina and has been tipped for a move to Europe.
Celta recently had a €5.5m bid for 50% of the player’s pass turned down by River and did not follow up.
Fiorentina have now made a formal offer of €12m that would also have some bonuses and a sell-on clause.
The proposal is described as ‘irresistable’ and more than likely will lead to Martinez-Quarta’s sale.
Martinez Quarta is a key player for Marcelo Gallardo’s side, but the financial realities have always pointed to a sale.
A two-time Argentine international, Martinez Quarta will soon be showing his talents in one of Europe’s top leagues.
