One the greatest sights in football is of a young, homegrown player transforming from the club's gawky, boot cleaning apprentice into its big bollock-swinging Main Man, and the star of that particular script this season has undoubtably been Man United's Marcus Rashford.
In an eye-wateringly expensive team of superstars with more draws between them than a branch of IKEA, the 19-year-old academy product has emerged as Jose Mourniho's main leading man, helping to fill the humungous gap left by Zlatan Ibrahimovich since his horror injury last month.
So it proved again last night during the club's tricky Europa League semi-final enouncter away to Celta Vigo, where Rashford curled in an exquisite freekick that, in its insouciance, reminded you of Federer smugly whipping an unstoppable forehand, or perhaps Salt Bae seasoning a steak.
Anyway, it wasn't scoring the crucial winner – his 19th and first from outside the box for United this season - that most impressed eagle-eyed fans, but the way that, when having to limp off with a (hopefully minor) injury in the 80th minute, Rashford dismissed the opposition players who were trying to make him hurry up.
"Are you the ref?" he asked the Celta Vigo player getting on his case – none other than ex-Man City player John Guidetti, no less – before giving him a dismissive wave.
It's the kind of cockiness you can only really feel as a 19-year-old who has just scored a blinder in an important cup tie, really.
After the match, Joe poured praise on his young star.
"He is a 19 year old kid that's in love with football. A kid that finishes training sessions and stays a half an hour longer to practice taking free-kicks. He works, he works, he works. Let's forget the age because what matters is the quality."
And who Jose is praising a homegrown player with flair, you know the kid is doing something right.
