Marcus Rashford became an instant hero for Manchester United after stepping in for the injured Anthony Martial.
The Frenchman was injured in the warm up against FC Midtjylland, and Marcus Rashford, on the bench for the first time, was called into the starting line up.
He made his impact in the second half, scoring twice to help the Red Devils to a 5-1 win on the night, and a 6-3 aggregate victory over the Danish champions.
With the extent of Martial's injury still unclear, Rashford could have a role to play against Arsenal on Sunday.
Former Gunner Ray Parlour is hoping he is left on the bench, commenting on Twitter about the 18-year-old's performance.
Great seeing a kid come through the ranks and have a blinder on his debut. 2 goals so far. Well done Marcus. Have a rest Sunday thou— Ray Parlour (@RealRomfordPele) February 25, 2016
United's forward options are limited so there is a strong chance Rashford will feature in some shape against the Gunners. If they are trailing or looking for a winner, he proved there is little downside and a lot of upside to throwing him on and giving him a chance - but at the same time, Arsenal's defence will provide a far sterner test than Midtjylland's.
