The Blues won again yesterday against West Ham United.
Cech admits even he was taken aback by such a fantastic start.
He said: "We could expect to pick up nine points with the relatively easy draw, yes.
"But the fact we scored 14 goals and kept a clean sheet in each game was hardly expected by anyone.
"At the moment I am most satisfied with our winning streak and with the fact we have been doing well as a team."
