Palermo president Maurizio Zamparini is in London today for talks with Arsenal.
Zamparini is attempting to close a deal for Gunners striker Joel Campbell.
Palermo see Campbell as a replacement for Paulo Dybala, who has signed for Juventus this summer.
Zamparini has already failed with one bid for Campbell, but is determined to bring the Gunners attacker to Sicily.
Sky Italia says the president is remaining in London today with the hope of getting a deal done.
