Willian is yet to agree a contract extension at Chelsea and is free to negotiate with potential suitors as he has less than six months left on his contract.
With the Brazilian's current deal expiring in June, he could be set to sign for another club on a free transfer come summer.
But, despite still being a useful option, it seems Chelsea are unwilling to meet Willian's reported demand for a three-year extension.
Arsenal could be given a helping hand by Kia Joorbichan, the agent who brokered David Luiz's move from Chelsea.
Joorbichan, who is himself an Arsenal fan, is the owner of the agency that handles Willian's affairs and may be influential in any deal.
The Tottenham faithful would take some convincing, however, after Willian famously rejected the club at the last minute in favour of rivals Chelsea when he first moved to England.
Both Arsenal and Spurs may face stern competition from Bundesliga big-hitters Bayern Munich who are also believed to be monitoring Willian's situation.
