We need to stop comparing him with Ronaldo. I doubt a 21 y.o Ronaldo would have been able to carry us against Barca in a team like this (and without Fergie as well). But Ronaldo's decision making at 21 was better than most 26 y.o. He's reached maturity faster than most, even Fergie said it himself. I can see Rashford improving but let's not use younger version of Ronaldo as an excuse for him.
