Petr Cech has been appointed as technical and performance advisor at former club Chelsea.
The Czech Republic international spent 11 years as a player at Stamford Bridge, winning 13 trophies, including four Premier League titles and the Champions League.
Cech, 37, joined London rivals Arsenal in 2015 and retired after their Europa League final defeat by the Blues in May.
He 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."
