One year on from a stunning brace against Arsenal, Marcus Rashford has become a crucial member of Jose Mourinho's Manchester United squad.

That Marcus Rashford’s quite phenomenal first three days as a Manchester United first-team player feels like way over 12 months ago is testament to the transition he has made from boy to man.

This time last year the teenager - largely unheard of and definitely untried - was scoring twice in the Europa League after a surprise call-up and then followed that up with a brace against Arsenal.

Roy of the Rovers stuff and from those whirlwind 72 hours United knew they had one for keeps.

Worries about how Jose Mourinho would treat Rashford were quickly quashed earlier this season and here stands an integral member of the Portuguese's squad.

While others have been in and out, the striker has remained a constant in the matchday 18. He’s missed just eight games all season which, for all Mourinho’s tinkering and plethora of options, is to his immense credit.

He remains raw and has not scored the number of goals United would’ve hoped this season but the way Rashford carries himself has impressed those around the club.

Just three days earlier, Rashford again scored twice on his senior debut against Midtjylland in the Europa League having been drafted into the squad from relative obscurity
