The Spaniard, seen as the architect of recent domination of the Europa League by his former employers, has completed a move to the Serie A club
Roma have confirmed the appointment of Monchi as their new sporting director.
The Spaniard – celebrated for his work in La Liga with Sevilla over the past two decades – has signed a four-year contract, with an option for a fifth year.
Monchi will begin working in the Italian capital with immediate effect, having been long linked to the Serie A club.
"I would like to thank Roma president Jim Pallotta and the club's executive team for giving me this opportunity," the 48-year-old former goalkeeper told Roma's official website.
