Chelsea have confirmed the appointment of Petr Cech as the club's new Technical and Performance Advisor.
Cech retired from professional football after last month's Europa League final which saw Chelsea crush Arsenal 4-1 in Baku.
The match represented the final game of Cech's illustrious playing career which saw him make 443 Premier League appearances, keeping a record 202 clean sheets.
'I feel very privileged to have this opportunity to join Chelsea FC again and help create the best possible high level performance environment to continue the success the club has had over the past 15 years,' said the 37-year-old.
'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.'
Chelsea director Marina Granovskaia added: 'We are delighted to welcome Petr back home to Chelsea. During his playing career here he was one of the most dedicated, successful and thoughtful professionals we have ever had.
'We always hoped that when Petr was ready to retire we would see him back at Chelsea FC and we are thrilled to add his expertise and knowledge of the game to the technical staff.'
