Liverpool are on alert after the agent of Mario Suarez fired a warning at Fiorentina management.
Suarez has been dropped for Fiorentina's trip to Europa League opponents FC Basel tonight.
The midfielder, who only moved to Florence from Atletico Madrid in the summer, is being linked with a January move to Anfield.
And agent Manuel Garcia Quilon told FirenzeViola.it: "Mario is happy to have chosen Fiorentina and there is no case, but he wants to have more chances.
"He's playing less than he expected and wants to have a chance to show everyone his value.
"The omission? I do not want to go into these issues. I do not know what happened exactly with (coach Paulo) Sousa and therefore I refrain from commenting.
"The market? Think of this. Mario Suarez wants to play more. Full stop."
