Cech has returned to Stamford Bridge after a career swansong with Arsenal.
He told the club's website, "It has been an amazing journey.
"If you are born in Czechoslovakia behind the Iron Curtain then you have a completely different perspective on life. Then suddenly when the revolution came and the borders opened opportunities came, and that played a big part for me because of the opportunity to go abroad or to travel to national tournaments.
"You start with small clubs and then you go step by step to the national team. This was my dream, to play for the national team and I wanted to play in the top division. Once you have that you want to play in the Champions League and at the age of 19 I did that and I started playing for the national team and then you think okay, what is the next step. That is to go to a top league and via France I ended up here and this is where my dream came true."
