The Czech Republic international thinks the training ground work is giving Chelsea players increased confidence on the pitch.
Villas-Boas has come in for some criticism since he moved to Stamford Bridge, but Cech is more than happy with what he has seen.
“Every manager is different but the people identifying problems at the club are making those judgements from the outside,” he said to the Daily Mail.
“They are never at the training ground. They never see what we are doing on a daily basis. I know that everybody is looking only at the results, but sometimes it is not always a reflection of what is happening.
“Everybody with Andre is talking about his age when in football there is no such thing as age. There is only quality.
“It's about the talent, quality and character of the individual. Edwin van der Sar was still a top, top goalkeeper at 40.
“If you have the quality and the character to win things, and the manager won with a big club like Porto, then I am not worried about the age. He has the experience.
“Whether you like or dislike a manager is not important.
“There have been so many managers I have not liked but I might have liked the way they are working; the way they prepare the team, the way they organise the training.
“If they understand the game, I am happy.”
Cech was at fault for the equaliser in the Blues 1-1 draw at Wigan on Saturday and he will be looking to rectify things in their next fixture against Tottenham on Thursday night.
