A loan to a good PL side would do him a world of good but people are greedy, they want him here & performing. I've seen this over the years with many of our young talent. When someone suggests a loan it is shot down and in the end those players fade away only for a new one to take his place. From my point of view a good loan is always a good option for a young talent. Crucial game time and broadening of perspectives of how football works in the lower tier. There are obviously arguments against but its rather subjective and dependent on the player but quite a lot of great players went on loans to hone their skills. Rashford unfortunately can't go on loan because we simply have just enough of space for him.
