Erik ten Hag hailed Manchester United's last-gasp hero Alejandro Garnacho - and then warned he is facing "danger".
Garnacho, at 18 years and 135 days, became the youngest player to score an injury-time winner in the Premier League since Federico Macheda in April 2009 when he was 17 years and 226 days.
Argentina wonderkid Garnacho did not make his nation's World Cup squad and Manchester United boss ten Hag admitted the break for the tournament will stop his momentum.
