The 51-year-old Argentine had been widely expected to take the Chelsea job, which is considered one of the most high-profile positions in European football.

Pochettino is no stranger to London after having a five-and-a-year spell with North London side Tottenham Hotspur. It will be his first coaching role since last July, when he left Paris Saint-Germain.

“Mauricio’s experience, standards of excellence, leadership qualities and character will serve Chelsea Football Club well as we move forward,” Chelsea said on its website.
