Van Gaal reveals what inspired stunning Rashford debut

By Coral Barry

Louis van Gaal has revealed his half-time instructions were the reason behind Marcus Rashford’s two debut goals.

The 18-year-old lead a stunning comeback for Manchester United as the Red Devils fought back from one nil down against FC Midjtylland in the Europa League to eventually win 4-1.

Both of Rashford’s strikes came from the youngster prowling in the box and speaking to BT Sport after the game, Van Gaal explained that it was his half-time chat that inspired the performance.

He said: “Unbelievable.

“In the first half he ran too much down the sidelines and I said at half-time ‘you have to been in the width of the goal and then you shall score’. And then you see that he scores two goals.

“It’s fantastic for him.”

Old Trafford were initially stunned when a goal just before the half hour mark from Pione Sisto had given Danish side Midjtylland an unlikely away advantage to put the visitors 3-1 ahead on aggregate.

But then goals from Ander Herrera and Memphis Depay wrapped up the game for United, after an own goal had gotten them back into the tie.

Missing Martial: The Frenchman’s absence was barely felt as Marcus Rashford stepped in

Remarkably, Rashford was a late inclusion after Anthony Martial injured himself in the warm-up.

United clash with Arsenal on Sunday in a crucial game and with Wayne Rooney also on the sidelines, Van Gaal was quick to dismiss fears over Martial’s availability.

He said: “It is a muscle injury, but I think he was smart.

“He was wise to step out because it was not a rupture or anything like that. He just had a tight hamstring. I don’t it is very serious.”

United are currently six points off the final Champions League spot in fifth.
