Rashford still hasn't extended his contract with Manchester United and it must be getting more worrying for the team on one hand. Because Rashford has made a huge progress recently. Under Erik ten Hag's management he has improved his performance a lot. He has made a huge level of contribution to the team with goals and assists throughout the season.
Although Rashford has made several contribution for Manchester United, but he's just an average above player, he's good but not that good. Rashford is a left winger player, Manchester United don't need to worry because they still have Sancho and Garnacho which play are left winger players too.
Manchester United need to find a good striker, they're still lack a player in this position.
Rashford has become a player who could fill in the void for Manchester United up front, especially in terms of scoring goals. He has managed to transform into a player who can contribute amid Manchester United's difficulty finding players who can do that within the squad they have. Actually I see the chances of him staying and leaving 50/50, in a sense the chances of him leaving and staying are just as great.
