The defender's contract at Stamford Bridge runs out at the end of the season, meaning that he will be free to negotiate a pre-contract with overseas clubs in January.
Speaking to The Guardian, the German international said: "The most important thing is that I feel happy here [at Chelsea]. I think if people look at it, they can see I'm happy."
Rudiger also confirmed that discussions were ongoing about a new deal at Chelsea, adding: "About the contract situation, I talk with the club. This is for nobody's ears. It was how I said it would be after the Euros – there would be talks.
"There was a talk between Marina [Granovskaia] and my agent. We have the situation where we are at now and I have nothing to do with all the speculation.
"This is not in my mind. I'm focused on what I'm doing because this is why I wake up every morning."
The 28-year-old has missed just one Premier League game so far this season, with the Blues currently sat top of the table. body check tags ::
