Emery was in London on Monday to finalise talks with the Gunners.
The Spanish coach left his job at PSG earlier this month.
Various reports have confirmed that Arsenal will confirm the appointment of Unai Emery as the new Arsenal boss.
Charlie Nicholas says that Unai Emery has an edge over Mikel Arteta because of his managerial experience and says that he is the right man for the Emirates faithful.
The 46-year-old Spaniard won 3 Europa League titles during his time at Seville and then led PSG side to a domestic treble this season.
He had to leave the French capital since he did not have his two-year contract extended and was replaced by former Dortmund boss Thomas Tuchel.
