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.
But his contract is still ending by the end of next season. This can even encourage some top teams to make an offer for him this summer. I wouldn't expect Manchester United to sell him of course but I wonder if Rashford would think of it.
The situation with Rashford's contract extension has become a worrying issue which needs to be attended to immediately now that the season has ended. Erik Ten Hag will not want to lose his key player for the coming season and the club will move quickly to sort it out and get this problem out of the way. I am pretty sure Manchester United are interested in keeping him longer in the club.
