Cahill insists he still has plenty to improve to match his captain.
He told the London Evening Standard: "As for John, I have learned a lot from him and I'm fortunate to have played a lot of games with him at Chelsea. This year he has started really well and I will always listen to him whenever he's got some advice.
"I'm sure he will go on for the next few years playing at this level. Of course I want to be like him. He's still playing at the highest level at 32. I'm 27, so that's where I want to be."
