I can understand your thoughts about Mason Greenwood but selling him might not be the best idea. He is talented player who could help team especially as backup for Rasmus Hojlund. He is a good goal scorer and has a strong left leg. On the other hand Jadon Sancho is not working hard and is causing problems. If he won't apologize and try harder it is better for team to let him go. He's lazy and focuses too much on partying, which isn't what Manchester United needs. Team should choose players who care and work hard like Greenwood over ones who don't try their best like Sancho.
I agree with you because Mason Greenwood has good capacity when playing and maybe Manchester United needs to give him another chance.
The more front players it will be, the easier it will be for Erik Ten Hak to make substitutions so that the players' motivation to be consistent will be boosted because there are other players who will take their place if they don't play consistently.
The performance of Jadon Sancho and Mason Greenwood is different, I like Mason Greenwood more than Jadon Sancho because he is a hard worker on the pitch.
Manchester United needs players who are willing to work together and are not selfish because this season we can see how Erik Ten Hak's men are more selfish and do not want to show teamwork.
A serious minded, focus, determined and committed player is what United needs, and this is where Mason Greenwood comes in, because he will be a better striker than Sancho is is arrogant and lack respect for his Boss. Any player that cannot be submissive to his manager will not be a good player on the pitch because he will not listen to instructions and that can also hinder the club performance in any match that he is playing. United need players that will work as one in unity with the coach so that the players bond will be very strong on the pitch for them to be able to defeat their rivals.
