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.
He's not entirely wrong. When Madrid meets formidable opponents, they struggle. Against less formidable teams they crush them. That is not the level of consistency Madrid is known for, Madrid is a team that excels when they face strong opponents. The last 5 games they've played have been against weak teams. I'm not downplaying their wins, but I'm only saying they have to maintain this level against good or in-form teams to conclude that they've been consistent.
As for Vini and Mbappe, I don't think we can call that linking well. It's Rodryo and Mbappe that have been linking very well recently, then Bellighma and Mbappe.
Vini and Mbappe have been showing signs of what could be, but they're not there yet.
