Football’s worst kept secret is out – Arsenal have officially confirmed Unai Emery will become the club’s new head coach.

The former PSG boss joins the club after completing a two-year spell in Paris, winning the treble of Ligue 1, Coupe de France and the Coupe de la Ligue, to go with his victories in the Coupe de France and Coupe de la Ligue the year before.

Unai, 46, had spent three years with Sevilla, leading them to a trio of Europa League titles.

Chief executive Ivan Gazidis said: “Unai has an outstanding track record of success throughout his career, has developed some of the best young talent in Europe and plays an exciting, progressive style of football that fits Arsenal perfectly.

“His hard-working and passionate approach and his sense of values on and off the pitch make him the ideal person to take us forward.

“We conducted a confidential, wide-ranging and rigorous search involving extensive background references, data and video analysis, and personal meetings with all the candidates we shortlisted. All were interested in the position and we were unanimous in our choice of Unai to drive the next chapter of our history.”
