Super agent Mino Raiola has been spotted in London today.
Raiola takes care of Manchester United midfielder Henrikh Mkhitaryan, who is set to join Arsenal in a swap for Alexis Sanchez.
Calciomercato.com says Raiola is in talks with the Gunners to thrash out personal terms.
Sanchez has already agreed to join Manchester United on a staggering £505,000-a-week deal, with Mkhitaryan moving the other way.
In his press conference today, Gunners boss Arsene Wenger confirmed Sanchez, 29, was being swapped with Mkhi, 28.
He said: "Yes that is my understanding. I like the player.
"The wages will not be a problem."
