Real Madrid must exercise caution in their match against Bilbao, though, as Vinicius will not play due to his suspension for receiving yellow cards in the previous game. Instead, Rodrigo will play the position, and Brahim Diaz will play on the right wing, ensuring a potent offensive. If Real Madrid plays lightly against Bilbao, they will not be happy with the result, as the team is dangerous these days, particularly with regard to the two Williams brothers who must be well-marked in order to deny them a chance to score.
Though real Madrid stand on a very higher chance to win the match but since Vinicius will not be playing the match they will need to be very caution on that match because since Bilbao has known that real Madrid attacking force is normally piloted by Vinicius and seeing that he will be absent on this match they will try as much as possible to to take advantage of the opportunity but though one thing i like about real Madrid is that in as much as Vinicius is a very important player on the club they also have other good players that will cover up in other for them to remain the way they are, so actually considering how consistent real Madrid has been I have a strong confident they will win Bilbao.
Bilbao is quite strong team and could show surprise in this match, I agree that Real Madrid must be really careful and play more with defense as priority because Bilbao has pretty good front line.
When it comes to Vinicius, this actually doesn't have much of an impact because it is clear that there are other players who can replace his position and there are several attacking players that Ancelotti can still rely on.
Moreover, no matter how bad Real Madrid condition is, they will still have strong enough performance and Ancelotti experience can enable Real Madrid to continue playing well and win the match against Bilbao later.
Conditions like this have happened very often with Real Madrid, even this season they have experienced player crises several times but were still able to show their best performance.
