Bruma spent four years with Chelsea, from 2009 to 2013.
"He has won everything in this sport and would perhaps give his life for Chelsea to just retrieve a ball from the goal line," declared the young Dutchman.
"He helped me a lot when I first came to Chelsea and took an interest in me. Both inside and outside the field."
Bruma added: "Last year he had a lesser period, partly due to the trainer changes. Now he is doing very well and makes few mistakes. I certainly have a lot of admiration for him."
