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 scores 30 goals this season and this is his highest goal records during play for Manchester United and Ten Hag apparently has successfully to optimizing the abilities of Rashford because since Ten Hag arrived and Rashford was playing regular for Manchester United he hasn't stopped to scored goals so i am sure Ten Hag don't want to losing him because Rashford is important player for this team
Indeed Rashford contract will ended on 2024 and Manchester United will attempt to give him contract extension and it was under progress but Ten Hag want the contract will signs this summer and the rumour is Manchester United will give him long duration contract for 5 years or more and obviously his salary will be increases and i am sure Rashford wouldn't reject contract proporsal from Manchester United and he will agree to extended it
