The 27-year-old has penned a five-year deal with Cesc Fabregas's ambitious side, who will play in the Champions League for the first time this season.

"I can't wait to bring my experience to the team, feel the incredible atmosphere at the stadium, and connect with the fans," said Chalobah, who made 151 appearances for Chelsea.

"I will give my absolute all every single day to make history together."
