Chelsea co-owner, Todd Boehly has hailed the arrival of Denis Zakaria.
Zakaria joined the Blues on a season-long loan deal with option to buy on transfer deadline day.
The midfielder had a medical in Turin on Thursday evening, with the deal being confirmed in the early hours of Friday morning.
Boehly told the club’s official website: “Denis is a talented midfielder with lots of quality and skill.
“He will add depth and range to our squad this season, and we are looking forward to watching him play in Chelsea blue.”
Zakaria joined Juventus in January from Borussia Monchengladbach, but only made just 15 first-team appearances
