Losing Militao for a long time due to a muscle injury does have a bit of an effect because it can be said that Madrid is struggling to replace some players even if we realize some of what Madrid did in the previous 2 games against Napoli and Osasuna even Tchouameni was played in the defender position because of the lack of players there due to injuries but looking at the the win against Napoli and the massacre of Osasuna I think it's still possible for Madrid to force it and they can still get 3 points against Sevilla although it's like I said before where rotation is also important because they are currently lacking defenders so this could be a difficult thing for Madrid if they continue to force Rudiger or Tchouameni in defense.
In as much has Madrid has suffers much injuries recently it's suprising how it has not really affected them in an obvious manners the rotation mechanism seem to be working smoothly for them with little or no hitches, they still have huge wins both in the UCL and La Liga, they maintain some level of consistency and their positions on the various standings regardless of their challenges.
Currently I think Madrid now have a full squad except for two players who are still at injury but vinicius is back and Bellingham is aswell present, the only challenge now would be that Madrid will be having more injury prone players and this could possibly affect them in the nearest future but then I think by the next transfer windo they will be getting good substitutes and replacement for these players if need be . Madrid is still in the race and very likely to be the champions of the UCL this season if they could continue with their consistency.
