Bruno Fernandez and Marcus Rashford played better after Cristiano Ronaldo left the club. They have less pressure and demand from Cristiano and they no longer have to share space on field with Cristiano. They are more free to play after that and their performance becomes better.
The only bad point in Manchester United now is Jadon Sancho. Ten Hag has yet successfully to revive Sancho after all but he is still young and has a long contract with United.
Bruno Fernandes in particular really seems to be enjoying the game more in every game after CR7 left MU. at least it has a positive impact on the team. and when talking about Jadon Sancho, it seems that even Erik Ten Hag is confused. Because Sancho has not been able to show good consistency. There was even news that Sancho was threatened with leaving MU. But it seems Sancho is still given the chance until the end of the season. And I personally see that Sancho does have good potential. But I don't know what made Sancho what he is now.
