A host of top European clubs are monitoring Gilberto Silva's situation at Arsenal, skysports.com understands.
Gilberto is believed to be considering his future at Emirates Stadium after enduring a frustrating campaign last season.
The 32-year-old struggled to hold down a regular place in Arsene Wenger's side last season due to the form of Cesc Fabgregas and Mathieu Flamini.
The Brazilian international has previously intimated he may have to move on if he is not playing regular first team football at this stage of his career.
The news has alerted several sides across Europe with Greek side Panathinaikos, Valencia and Juventus all tracking the midfielder.
Gilberto, who has one-year left on his current contract, is set to discuss his future with agent Frank Trimboli when he returns from holiday later this month.
Wenger would be loath to lose Gilberto having already seen Flamini leave the club this summer, but he could face a fight to keep the South American out of the clutches of rival clubs.
