Unai Emery, 46, was shown the exit door by French Champions, Paris St German at the end of the season, despite winning the domestic treble and will replace Arsene Wenger at the Emirates Stadium.
The Spaniard emerged as the shock favourite earlier this week after it had seemed former Arsenal captain Mikel Arteta was in line to land the job.
Instead the role has gone to Emery, who won three successive Europa League titles with Sevilla before moving to PSG in 2016.
Below are the 10 facts you probably didn’t know about the incoming Arsenal coach:
1. Unai Emery is only the second non-British manager of Arsenal in their history, after Frenchman Arsene Wenger
2. Emery will take charge of his seventh club and his sixth in the top-flight since he moved into management back in January 2005 with third-tier side Lorca Deportiva.
3. His spell at PSG was his most successful in terms of league performance – it was his first ever top-flight league title and saw him achieve his best points per game (2.37) and win ratio (74%).
4. He became the first-ever Spanish manager to win the French Ligue 1 title, with his 2017-18 success with Paris Saint-Germain.
5. Before joining PSG, Emery had never finished higher that third in a top-flight league season (in both 2010-11 and 2011-12 at Valencia).
6. Unai Emery’s 73.7% win ratio and points per game ratio of 2.37 is the best ever seen in Ligue 1 by a Paris Saint-German boss.
7. Unai Emery won seven of the eight domestic competitions he has managed with Paris (Trophéedes Champions x2 Coupe de la Ligue x2, Ligue 1, Coupe de France x2). Only Laurent Blanc (11) won more trophies at the club.
8. He’s never won a competitive game against Pep Guardiola (10 games) or Jose Mourinho (5 games).
9. By winning the UEFA Europa League in 2013-14, 2014-15 and 2015-16, he became the only Manager to have won it three seasons in a row.
10. Emery, a left-sided midfielder, was a youth graduate of Real Sociedad, but never really broke into the first team (aged 24 he appeared in five La Liga games, scoring against Albacete Balompié in an 8–1 home win). After that, he resumed his career mostly in the Segunda División, amassing totals of 215 matches and nine goals over seven seasons.
