The homegrown hero broke the deadlock after six minutes with a powerful finish that beat the Spurs goalkeeper at his near post and he could have netted two more goals in the first half, after hitting a thunderous shot that almost broke the crossbar before thumping a free-kick just wide from range.
The visitors equalised through Dele Alli on 39 minutes but, undeterred, Rashford maintained his performance level in the second half. Almost immediately after half-time, he won a penalty in front of the Stretford End. Despite a lengthy wait for VAR, he duly slotted it home into the bottom corner of the net.
