The Blues' 0-0 draw with the Toffees left Guus Hiddink admitting they would not be able to catch leaders Manchester United, sentiments Cech has now echoed.
While Chelsea can mathematically catch United, the Czech Republic ace cannot see Sir Alex Ferguson's dropping enough points for the Blues to mount an unlikely charge.
Realistic"Mathematically it is not finished, but we have to be realistic and I can hardly see Man United dropping nine points for us to go in front and we can't forget we are a few points behind Liverpool, who are closer," he told the club's official website.
"If Man United slip and have a bad spell we are not the closest one to gain from that, so I think now with their one game in hand it is stretched too far in front of us.
Meanwhile, Cech says he will be fit for Chelsea's trip to West Ham on Saturday after being caught by Jo at Stamford Bridge.
The pair collided late on forcing Jo to be substituted, but the Blues shot-stopper insists there will no lingering damage from the challenge.
Knock on the nose"I got a knock on the nose so it is sore but nothing too dramatic," he continued.
"I knew that we were going to clash because the ball didn't bounce too high or low - I knew I had to put my head in there, it was the only way I could get to the ball first, and as soon as I headed the ball I put my arm across to protect myself.
"But that stopped him from moving and he did the same thing, so his elbow caught me straight on the nose."
