What do you mean by 'reach his potential?'
He literally has more goals and assists than Ryan Gigs at the same age. Than Ronaldo at the same age. Than Rooney at the same age. Then ANY of the hundreds of academy graduates we have ever brought through our football club had at the same age, be teh name Charlton, Best, Whiteside, Edwards, Giggs or Scholes ...
The kid is fecking awesome.
I swear, if you think Rashford is an inconsistent player, then I would have loving to have got your opinion on Giggs when he was the same age. In 1995, you'd probably have wanted to swap Ryan Giggs for Thomas Brolin. Denying us our greatest and most loyal player in our entire history.
You don't judge football week-to-week, my friend. You need to have a much bigger vision and more open mind than that. I bet if you met Sir Alex Ferguson in the street and you told him you'd swap Marcus Rashford for Mbappe, he would laugh at you while shaking his head, then he'd say 'deary, deary me, son.'
