Huh I'm sorry I didn't look at the schedule and Barcelona are playing at home in this first El Clasico. but isn't this better? The odds are bigger with the belief conditions not changing for Madrid 
But indeed Barcelona are favourites it is also quite reasonable because playing at Camp Nou with their current condition that looks still fine even though there are some problems that occur there still they are Barcelona who are indeed strong and this is an El Clasico with high prestige.
As for Lewandowski, he still lacks momentum and this clearly affects especially now when he can play later for Barcelona there will definitely be a readjustment after several weeks of not playing due to injury, obviously this will disturb him.
Joao is still in the adaptation stage but indeed the performance he showed was still very good and I think this exceeded the expectations of some people so that this could be a problem if it was too much to let.

Maybe Barcelona has an advantage due to the fact that the game will take place at the Camp Nou, but in my opinion it is not so that Real's quote is 3.00
As for Felix, he plays as always, he has already adapted
He is always active, fussing, has chances, but usually there is very little benefit from this in the form of goals. There was another such game against Slovakia, although he had little playing time.It will be difficult when their players are forced to continue playing because fatigue could also be a factor in this.
The most likely condition is to apply rotation for matches in the Champions League because their points are also quite safe, but it also cannot be used as a stumbling block because when they lose this can b e a condition where momentum is lost.
Now it's up to the coach how they organise the plan and this is quite a heavy burden even though their opponents (Madrid and Barcelona) are still not too tough, it will still be troublesome if they can't organise the rotation properly.
