Video: Watch Marcus Rashford's Penalty Seal Manchester United's Comeback vs. PSG

Manchester United's 3-1 victory over Paris Saint-Germain in the second leg of their Champions League showdown didn't come without drama—and some controversy.

After dropping the first leg 2-0 in February, the Red Devils were down one goal on aggregate in stoppage time. Then, a controversial handball set the stage for 21-year-old Marcus Rashford to stun PSG in the final moments with a clutch penalty kick.

Just like that, a 3-1 victory and three away goals sent United on to the quarter-finals.
