Cech wants long-term future with Chelsea
Cech was criticised earlier in the season when Carlo Ancelotti's men were conceding goals from set-pieces, but he has been back to his best recently and in the Barclays Premier League victory over Arsenal last week produced crucial saves.
The 27-year-old has a contract until 2013 and, when asked about spending the next 10 years at the club, said: "If I stay fit, at least as I am now, then I'll play as long as I can because this career is normally pretty short and everyone wants to make the most of it."
He added: "It all depends on how fit you stay and how well you play because suddenly you're not as fast and your reaction is not the same.
"You can compensate it with a bit of experience, but there always comes a point when you know it's not going to be the same, so it depends how long this is going to take."
Cech has helped Chelsea win the Premier League twice but is yet to enjoy Champions League glory - and if they are to win it this season they will need to get past former boss Jose Mourinho.
Cech will travel to Italy next week for the first leg of the last-16 clash against Mourinho's Inter Milan.
Chelsea are currently top of the Premier League but Cech told Chelsea Magazine: "Always the Champions League is our aim and you can see that we've been playing for it every season and we've gone far, but the aim is the same.
"The Champions League is the only trophy this club is missing so I think that is what everyone would like to win."
He added: "For the fans, for the players and for everyone linked with the club, I think it is going to be a special occasion (against Inter)."
