LONDON -- There was a time when Manchester United chancing their luck on a rookie striker would create a moment of folklore.
Most famously, think Federico Macheda against Aston Villa in 2009. Or Danny Welbeck against Stoke City two years earlier. And then there was Marcus Rashford's stunning full Premier League debut against Arsenal in 2016, scoring twice to offset an injury crisis under Louis van Gaal.
But as Sunday's 1-0 defeat at Tottenham ticked into stoppage time, Ruben Amorim opted to throw on 17-year-old Chido Obi-Martin for his senior debut.
