The defeat means our title celebrations were put on hold, with City still in need of three points from our final three matches to seal the deal.
It's the second time in quick succession Chelsea have beaten City, with our defeat in the FA Cup semi-final coming just three weeks ago.
But Guardiola says it will not matter when the Champions League final comes a long at the end of May.
"We have 21 days [before the final], he said
"We will see what happens in the final. It’s a different competition, we are going to try to play this game, we will analyse and play the final, which is a dream come true for us.
"Chelsea have been there many times, it's the first time we will be there.
"We are going to approach it in the best way possible.
"All I can say is congratulations Chelsea for the victory.
"We will go to Newcastle and try to win the Premier League. If not to Brighton, if not against Everton and then after we will go and prepare the final against them."
