It is too soon to say what is going to happen. Zidane has made Madrid very tight defensively and counts on a bunch of experienced players with quality, especially in midfield, but I feel the team is a little bit short upfront. It just doesn't make sense to base the attack on Rodrygo or Vinicius just to name a couple of players. I just cannot believe how this team is getting the results without Hazard, so credit has to go to the coach.
As for Barcelona, Suarez's injury completely changes the situation. It is early to judge Quique Setien but unfortunately for him he doesn't have much time left since his appointment was mostly made to force the team to react. Otherwise they would have kept Valverde until the end of the season.
