Eduardo has signed a new one-year contract keeping the goalkeeper at Stamford Bridge for another season.
The 34-year-old Portugal international joined from Dinamo Zagreb last summer and has been an important part of the goalkeeping set-up at Cobham that has allowed no.1 Thibaut Courtois to flourish in the title-winning campaign.
Eduardo said: ‘I am very happy to stay at Chelsea for another year. This season has been very successful for the club, and everybody has made me feel like a part of the family. I hope next season can be just as positive and we can win many more trophies.’
Technical director Michael Emenalo added: 'Since joining us last summer, Eduardo has been a model professional.
'He has used his wealth of experience at the top level to bring the very best from his fellow goalkeepers and has been a reliable, popular and respected member of the squad.
'We are delighted he has chosen to commit his future to Chelsea.'
