This your assertion of you thinking that Real Madrid has not proven to be better because you have not seen consistency in near performance simply shows that you are not watching Real Madrid games. And you saying Mbappe and Vini hasn't linked is further proof that you are not watching the team play, because if you were watching, you will definitely notice the difference between them now and the beginning of the season and also Real Madrid now and the beginning of the season.
There is a way you can mix some food as combo and enjoy them but till now, I haven't seen the connection between Mbape and Vinicious. No doubt, Vinicious gave him a lot of assist in the beginning of the season but what did he do, wasted it on Offside and no any goals and I think since then, I can see a lot decline from him, he does most of his things in his own but ever since Vinicious went to compulsory break, Mbape seems to be the lion for now.
To be honest, this combination of players in Real Madrid isn't palatable, I'm not sure if Anceloti is trying to create memories of the past players during the time of Ronaldo, Benzema, Zidane and some other legendary but this guys are worst including their counter El clasico guys. There will not be a previous Real Madrid that we used to have, it will take the next coach more time before he can figure it out the best way possible to put these guys together.
