The general consensus is that Marcus Rashford is a left winger and Rashford himself says that's where he prefers to play, and he hasn't developed under Ralf.
Rashford is a very talented player and I hope that Erik ten Hag can bring him back to life and understand the wishes of all Manchester United players, and besides that Manchester United desperately needs a striker who has the same talent as Ronaldo, so that Ronaldo always has a scoring opportunity.
Marcus Rashford potential under Erik Ten Hag must be even more developed than when coached by Rangnick. doesn't seem to show a lot of skill, which does seem like Marcus Rashford has something that Erik can develop. Many of the tasks of Manchester United's young players need to be reorganized. Besides that, playing on the wings did make Rashford more confident, so Erik could give that position as much as possible in order to maximize Manchester United's performance. Although in fact Rashford also needs a suitable partner.
Rashford is a right footer, young and talented. He should be able to play any position at the front to help the team. Why must it be left wing? From Manchester United academy, was it wing he was playing? He came as a striker and so also Martial, due to Manchester United is a wing club, they were made to adapt to wing.
Rashford is playing the wing game in order to play full 90mins. He knows he cannot bench Ronaldo. Then, if I were to be a coach, I cannot play Rashford ahead of Sancho. So, he can't easily pull Sancho off.
He should relax, remove laziness and bring out his mind to play for Manchester United.
