It is far too early to know where the Marcus Rashford story ends. Two games -- even two games in which he lit up a Manchester United wallowing in gloom and shade -- are no sample at all. He could yet burn with a bright but brief flame, as Federico Macheda once did, or this might be the early flickering of a fire that lasts for years.
There are too many twists, turns and roadblocks that could yet appear on his path. An injury could derail it all, and so could someone else's return to health. All the stardom might go to his head.
