He is doing more work than ever to ensure he stays in shape and can keep playing at Stamford Bridge for years to come.
He said: "When I was 21-22 I'd come in, train and go home. I would come in the next day and not think much about it. I looked at the likes of Gianfranco Zola and Dan Petrescu and they spent a lot of time in the gym and I didn't understand why.
"As you get older you do realise that a little bit of work before can help. I drop my kids into school at 8.30am every morning and I am probably the first in the training ground. I like to stay behind on the pitch as well.
"That is certainly going to put me in good stead in the long term. I have four years left on my contract here and I want to extend that. I'd love to set massive milestones at the club and continue playing at the highest level. I know there will come a point when I'm not good enough and there will be younger players or signings coming in to replace me.
"I'm big enough and old enough to accept that. But I will give it a right good go till the end."
