Willian says he would immediately sign a new contract if Chelsea agreed to give him a three-year deal.
The Brazilian, 31. is coming to the end of his contract and looks set to leave Stamford Bridge on a free transfer.
He has been offered a two-year deal but wants a longer-term contract.
Chelsea are reluctant to offer long contracts to players over the age of 30.
“My goal in the next contract is to sign for three years. So I haven’t had a deal with Chelsea yet.
“This is what I asked the club for, three years of contract. If you give me that, I’ll get the pen and sign the contract tomorrow.”
Tottenham and Arsenal have both been linked with Willian, who previously played under Spurs’ ex-Chelsea boss Jose Mourinho.
“There are rumours about several teams that may be interested,” the winger said.
“For the time being, I have had no concrete proposal. But rumours always arise.”
“I’m waiting. My agent hasn’t given me any news yet. I’m waiting for his call.”
