An elite club doesn't stand strong enough without holding on proper grounds in the transfer window. Real Madrid have a whole working to do and this simply the best team in La Liga. Real Madrid won the super cup when they thrashed Atalanta 2-0. This is absolutely one of the best squad any potential manager would wished for. Carlo Ancelotti have rearrange his team and planning on exploring his tactics because there's more to accomplish.
While their offensive line looks amazing that doesn't mean that their defense is equally strong at the moment. I believe that they really need to reconsider that part, I do not think that the talent gap between offense and defense is similar, the gap seems very big.
They can definitely get better players then Mendy, Rudiger, Militao and Carvajal there, not saying those are bad players but they are not like Vini or Jude or Mbappe level players, you need to have the best there. Imaigne if they had Davies like they wanted to, or imagine they had Trent like they requested information on, those are all big names and could be great. We need to just focus on how to get better and what we can do, otherwise their defense could cause some issues for them.
