Cech insisted Chelsea had no-one to blame but themselves after dominating for long periods at St James' Park.
The 31-year-old told Chelsea TV: "Apart from the wind, we can't blame anything. The pitch was very good, very fast, and actually it was good to pass the ball, so this was not the reason why we didn't win.
"There are no excuses, no pitch, no early kick-off, whatever. We didn't play well enough to win the game and that's why we lost. To be fair, they sat back because they were a bit afraid, so it was their plan.
"You could see from the start they wanted to congest the pitch and that's why you don't have many chances to make the tempo and the game really running.
"But to be fair, we had enough possession, we had enough comfort on the ball, but we didn't find a pass."
