Brazilian playmaker Oscar and Belgian winger Eden Hazard were among the six new arrivals and both have been impressive in the Blues' march to the top of the Premier League table after seven matches.
Cech is pleased with how the duo have adapted to life in English football and believes that it was not too difficult for them to do so.
"You can see that the players who are in our attack have all got used to each other," he told Isport.blesk.cz.
"They are good attuned to each other even if they play together for the first time. Eden is great with his technique and with Oscar they are a dangerous duo.
"Moreover, the Brazilian and Spanish style of football is similar, so even Fernando Torres is used to it.
"That is why, even if there are a lot of new players, they have found the common language on the pitch."
