I hope that Lampard can bring change to Chelsea, especially against Madrid, of course there is a lot to be prepared, especially overhauling and organizing better tactics, yes, even though I know it is difficult to make Chelsea in a short time better than before, but hopefully Lampard knows how way of making it even better because he had previously managed Chelsea before.

Your hope was not even coming true. Chelsea faces another lose again in the domestic league. The winner for the first leg can be determined easily. Chelsea is a mediocre club right now after it changed hands. No body may bet on chelsea at this moment.
The gap to the real madrid is too big. Chelsea will become a team that will be destroyed by real madrid in this match. It doesn't have good striker and its players are also playing like amateur football players.
chelsea is now having a mentality issue. This is also the main problem that will never be fixed if chelsea didn't get a good coach that will able to handle the club properly.
Lampard is failing right now. i don't even wanna try to hear any bad results from him anymore, 1 match is more than enough to know what's gonna happen next.
Instead of Chelsea having to focus on the Champions League to win, I even think they are better off focusing on fixing a situation that is currently really bad. Indeed, I understand that they also want to prove that they can still play well and can qualify by beating Real Madrid, but with what they have shown, will that come true? i don't think that will happen. Lampard has a tough job, I don't think he will be able to do the job quickly, it must have taken a long time. Long season for them with their performances like that.
I wonder what Napoli can do this season in the Champions League, in Serie A it is very clear that they are dominant and in a while they will be able to claim the Scudetto title. In the Champions League they actually have a big chance to be in the final match. AC milan will be their opponent in the semifinals, even though the last meeting they were defeated by AC Milan with a landslide score, but to be honest I can still say Napoli is still better than AC milan now. Their chance to beat as well as avenge their defeat in the previous game. If they pass this phase then it is also possible that they will face Inter Milan. I'm still waiting for the performance from Napoli this season in the Champions League.
