Rudiger: 'Chelsea can only improve'

"At the end of the day, the three points are more important because the performances will come definitely," Rudiger said to 'ESPN' after the game. 

"If I [look at] this game and the game against Arsenal in the first half and the last 20 minutes, we're improving. Game by game I think it's getting better and that's our target.

"Before the internationals, we'll try to win all of our games and then come back after and go on."

Rudiger also praised Chelsea's never-say-die attitude, after they scored a late winner to take all three points at St James' Park.  

"That's a good sign. It meant we are ready — it was a difficult game but in the end, with a bit of luck, we fully deserved this win. But if you saw the whole game, I wouldn't say that it's luck."
