Cech, Frank Lampard and Ashley Cole have all been linked with a move to the Spanish side.
“It is common to say ‘never say never’, and it always happens that, if such a coach is appointed at such a big club, plenty of potential targets appear in the press,” Cech told CTK.
“At the moment it is just at the level of big rumours and I don’t think it is necessary to comment on them at all.
“Speculation will always be there, but I don’t see it (a transfer) as being realistic.
“The goalkeeper’s position is the last area Real have to improve and that makes it the end of the story for me.”
He added: “I am happy there. The only major trophy that is left for Chelsea to win is the Champions League.
“And, in my opinion, at the moment we have a team strong enough to win the competition.
“As for my ambitions, I am satisfied and that is why I don’t intend to leave for anywhere.”
