Unai Emery was the “unanimous” choice to “drive the next chapter” of Arsenal’s history after being confirmed as the club’s head coach, says chief executive Ivan Gazidis.
Emery, 46, joins the Gunners having left French champions PSG after guiding them to the Ligue 1 title.
The Spaniard also won four domestic cups with the French giants, having previously guided Sevilla to three successive Europa League triumphs.
He succeeds Arsene Wenger at Arsenal.
The Frenchman left the club at the end of last season after 22 years in charge.
What has he achieved?
Emery announced last month he would leave PSG when his contract expired at the end of the season, despite leading them to the Ligue 1 title.
During his two-year spell with the French giants, he also won four domestic cups, having joined from Sevilla in 2016.
It was in his home country that the former Real Sociedad and Toledo midfielder made his name as a manager, taking charge at Almeria and Valencia before moving to Sevilla in 2013.
There he won three successive Europa League titles as well as finishing runners-up to Barcelona in the 2015-16 Copa del Rey.
