Speaking with the Players' Tribune, Robben hailed Terry's leadership - with the former Blues captain now playing for Aston Villa.
"The most important thing is how to be a leader. Terry will be someone with whom you can talk about football and many other things.
"He advises, he encourages. Learn as much from him as he provides everything for the club and takes care of every individual in the team. You will eventually have no idea how much John Terry's influence will have on you. You'll never play with anyone like him."
