As the latest reports would have it, Emery will be the one to occupy the manager's seat at the Emirates come next season after winning the Ligue 1 title with PSG this season, only to be replaced by Thomas Tuchel as a direct result of his Champions League failure.
Emery, 46, became available after leaving Paris-Saint Germain at the end of the 2017-18 campaign, having won the Ligue 1 title, two Coupes de France, two Coupes de la Ligue and two French Supercups during his two seasons in charge there.
However, while he is described as "not completely fluent" in English, that is not described as a problem, and his appointment is expected to be ratified shortly.
It comes with Arsene Wenger leaving the club after nearly 22 seasons in charge.

According to David Ornstein of BBC Sport, "an announcement and news conference are expected later this week" to confirm Emery as Wenger's successor.

Ex-Gunners captain Arteta had been tipped to lead them into the new era and is thought to have been chief executive Ivan Gazidis' preferred choice.
