Chelsea have confirmed the return of Petr Cech to Stamford Bridge in a behind-the-scenes role.
The former Blues goalkeeper, who retired from playing last month, has been given the position of technical and performance adviser.
Cech, 37, spent 11 years at Chelsea, winning 13 trophies, including four Premier League titles and the Champions League.
He joined Arsenal in 2015 and his final appearance was their recent Europa League final defeat against Chelsea in Baku.
Chelsea said the former Czech Republic international will “provide advice on all football and performance matters” and “facilitate strong links” between the academy and first team.
He will take on some of the responsibilities previously assigned to Michael Emenalo, who left his role as Chelsea’s technical director in November 2017 to join Monaco.
Cech said: “I feel very privileged to have this opportunity to join Chelsea again and help create the best possible high level performance environment to continue the success the club has had over the past 15 years.
“I’m looking forward to the new challenge and hope I can use all of my football knowledge and experience to help the team achieve even more success in the future.”
