Having already signed Willian from Premier League rivals Chelsea this season, Arsenal have reportedly contacted fellow Brazil international Oscar over a potential return to England.
Oscar left the Blues in January 2017 to join Chinese Super League side Shanghai SIPG in a £60 million (R1.2 billion) deal, but has been linked with a return to the Premier League after receiving an approach from the Gunners.
With Arsenal being home to Oscar's former Brazil and Chelsea teammates Willian and David Luiz, the 29-year-old recently admitted the club has been in contact with him through the pair over a potential move to the Emirates Stadium.
"They called me, they had to call me. Because we have good communication. Sometimes I talk to them. They said 'come to Arsenal, come here,'" the attacking midfielder told Fox Brazil.
"But for me, it's a little more difficult. I have a contract with Shanghai, it's a little more difficult to leave. Willian had finished the contract. I was happy that they got together again.
"And happy that Willian is happy. The most important thing is to be happy, regardless of the place. So I hope they are happy there."

"But the situation is difficult for me to return, it's a little more complicated for me to get out of here. So I hope to fulfil my contract here calmly and then, yes, I think about going back to Europe.
"Of course, the first club I'd choose if I could go back to Europe is Chelsea, for sure, which is the club that I built a very beautiful history with..."
