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.
Mason Greenwood is a good player and he was a player at a young age which means he is a gem but unfortunately, after the drama that happened at Manchester United for him, Mason Greenwood is not famous and he doesn't have any reputation in Manchester United.
All the Manchester United wanted him to leave the team and that's why he joined Getafe however he had a good performance there which made some other teams like Atletico Madrid to send him an offer while returning to Manchester United could be another option for him.
