Despite only featuring in the last 10 minutes, the young Uruguayan provided an assist for Marcus Rashford as the Reds went on to win 3-0, progressing to the semi-final stage.
In a recent interview, which features in our matchday programme United Review for the Premier League clash with Leicester on Sunday, Facundo reflects on a night he considers to be 'perfect.'
“It was incredible, because I had been looking forward to that moment for a long time," he said. “I was the one who enjoyed being on the pitch and wearing the Manchester United shirt and luckily there were 10 minutes more or less and I could touch the ball a lot and make that assist for Rashford.
