Rashford latched onto Luke Shaw’s pinpoint pass in the 11th minute and slotted the ball first-time past the advancing David de Gea.
Despite only starting one game in England’s journey to the World Cup semi-finals in Russia this summer, Henderson insisted Rashford is a key man for the Three Lions.
“We all know how talented Marcus is,” he said to Sky Sports News.
“His was a great finish.
“He had another one or two chances that maybe he would have liked to have scored but I thought he looked sharp.
“He was lively and he’s always a threat on the counter-attack.
“He’s a fantastic young player so he just needs to keep learning, keep improving. He’s a big part of our team.”
Despite the loss, Rashford’s goal would have been a silver lining for the 20-year-old after he got sent off in Manchester United’s 2-0 over Burnley last weekend for leaning his head into Phil Bardsley during an altercation.
Rashford could have added to his tally on Saturday but he was kept at bay on multiple occasions by his United teammate, de Gea.
In 2016, Rashford made the perfect debut to his England career, scoring just three minutes into it; the opening goal in a 2-1 win over Australia in the build-up to the European Championships.
He has since gone on to appear 26 times for his country, scoring four goals in the process including his goal against Spain on Saturday.
But perhaps his biggest moment so far in an England shirt came when he scored his penalty in England’s penalty shootout win over Columbia at the World Cup this summer.
