The 18-year-old sent Man United fans into ecstasy with an injury time winner against Hull City, drawing universal praise from supporters following a galvanising display from the bench.
In his column for the Daily Mail, Redknapp insisted that, should Rashford continue in the same vein, it would be impossible to leave him out of the starting XI.
“You can’t hold Rashford back for long, Jose,” he wrote.
“This kid is a juggernaut and will force his way back into the side sooner rather than later.
“I am also surprised to see he has been left out of Sam Allardyce’s first England squad. The 18-year-old is one of the most exciting talents this country has produced and showed in 21 minutes at the Euros that he is more than capable of performing at international level.”
Rashford provided everything the United side failed to deliver against Hull: he was quick, direct, imposing and most of all fearless, throwing himself – time and time again – at a knackered and bewildered defence until the breakthrough was made.
It was simply breathtaking, bordering on startling; this 18-year-old, unknown until late February of this year, encapsulates everything United fans – and indeed football followers as a whole – love to see in an attacking player. The sheer verve and power he has at such a young age is intoxicating, and it certainly merits a place in Mourinho’s starting XI.
