The Sky Blues have already clinched a spot in the next round of the Champions League.
"We are in the best 16 and now we are going to see the draw, and arrive at the right moment", Guardiola told BT Sport.
Croatia striker Kramaric, who has scored in his last eight games for club and country, said: "We are still hoping".
"After that we created an incredible amount of chances, but the result is good". We can enjoy the game.
However, it mattered little as the competition favourites march into Monday's last 16 draw where they can face Atletico Madrid, Schalke, Ajax or Roma.
But Silva's absence could be for a "few weeks", according to Guardiola.
City wanted more and Foden began to grow in confidence.
Sane said: 'I just regret we didn't score the goal.
Pep Guardiola expects his Manchester City side to learn from their defeat at Chelsea (Martin Rickett/PA Images).
"The managers are so good and the best teams in Europe are here", the City manager said.
"But we don't have a huge amount to lose".
"But I have no argument with the way we lost. It's part of the process and we have to learn".
Leroy Sane scored twice as last season's quarter-finalists reached the knockout round for the sixth successive season.
The German said: "Now every one is really motivated".
The hosts were finally level in spectacular fashion when Sane curled a free-kick into the top corner from 30 yards out.
The Germany winger then grabbed the victor in the 61st by exchanging passes with Raheem Sterling, taking a touch beyond Baumann, and slotting the ball into an empty net.
Sane, whose contract expires in 2021, is now in discussions over a new deal.
There have been reports that the 22-year-old could join Raheem Sterling and Phil Foden in signing a new long-term contract at the Etihad, and Sané has revealed that could be the case.
"They are all unbelievable but most importantly they are all incredible people and good characters".
"I feel really at home here from day one and of course it (staying longer) is possible".
